A tyre baler will last 15 to 20 years with proper maintenance. Without it, you’re looking at 7 to 10 years before major component failures force replacement or expensive refurbishment. The difference is preventive care.
Industrial hydraulic equipment doesn’t fail randomly. Seals wear gradually. Oil degrades. Electrical components drift. Bearings develop play. All of these problems are detectable and fixable if you catch them early. Left unaddressed, they cascade into catastrophic failures that cost thousands to repair.
This guide provides a complete maintenance schedule for Gradeall tyre balers, from daily checks to annual overhauls. You’ll understand what needs doing, why it matters, and what happens if you skip it. The schedules below are based on nearly 40 years of manufacturing experience and operational data from customer sites across 100+ countries.
Gradeall International manufactures tyre baling equipment at our facility in Dungannon, Northern Ireland. We support customers through the entire equipment lifecycle, from installation to eventual decommissioning. The maintenance procedures below keep MKII and MK3 balers operating reliably for decades.
Start each operating day with a visual inspection. This takes 5 minutes and catches 40% to 50% of potential problems before they cause breakdowns.

Wire feed mechanism:

What to do if you find problems:
Most daily checks are visual and auditory. You’re looking for anything abnormal compared to yesterday. Experienced operators develop an intuition for what’s right and what’s wrong. New operators should complete the checklist methodically until they build that intuition.
Hydraulic oil level top-up: Even well-sealed systems lose small amounts of oil through seal seepage and system venting. Check the reservoir sight glass weekly. If oil is below the midpoint between min/max marks, top up with ISO VG 46 hydraulic oil.
Add oil slowly (1 litre at a time) and allow it to settle for 5 minutes before checking the level again. Overfilling causes foaming and aeration, which damages pumps and valves.
Greasing pivot points: The baler has approximately 8 to 12 grease points: door hinges, ram guide bushings, wire feed rollers, and mechanical linkages. Apply 2 to 3 strokes of industrial lithium grease to each point.
Wipe away excess grease that squeezes out (it attracts dust and debris). If a grease nipple won’t accept grease (pressure builds immediately), it’s either blocked or the bearing is seized. Flag this for maintenance attention.
Wire feed mechanism clean: Wire debris, dust, and tyre rubber accumulate in the wire feed path. Use a brush and compressed air to clean the wire guide channel, cutter area, and tensioning rollers. Pay particular attention to the wire cutter blades; rubber buildup on the blades causes poor cuts and wire jams.
Hydraulic filter check: Most balers have a visual indicator on the hydraulic filter housing (typically green when clean, red when clogged). Check this weekly. If the indicator shows red or the filter is approaching change interval (see monthly maintenance), prepare to change it soon.
Baling chamber clear-out: Remove any tyre fragments, wire offcuts, or debris from the baling chamber. Accumulated debris interferes with ram movement and can damage seals.
Control panel clean: Wipe down the control panel with a dry cloth. Don’t use water or solvents on electrical controls. Clean buttons and switches improve responsiveness and prevent sticky operation.
Hydraulic filter replacement: Hydraulic oil filters capture contamination particles before they damage pumps and valves. Filters are rated by micron size (typically 10 or 25 micron for tyre balers) and have a service life measured in hours or pressure drop.
Change hydraulic filters every 500 operating hours or when the filter indicator turns red, whichever comes first. For typical operations (8 hours per day, 20 days per month), that’s monthly.
Filter change procedure:
Filter cost: £25 to £40 depending on model. Don’t use cheap aftermarket filters. They’re usually lower quality media that doesn’t filter as effectively.
Safety system verification: Monthly testing of all safety systems confirms they’re functioning correctly. This isn’t just good practice; it’s required under PUWER regulations.
Document safety system tests in your maintenance log. Include date, tester name, and results for each system. If any safety system fails testing, take the machine out of service until repaired.
Wire feed alignment: Wire feed misalignment causes jams, poor cuts, and inconsistent bale tying. Monthly alignment check takes 15 to 20 minutes:
Some wear on guide rollers is normal. Replace rollers when grooves exceed 2mm depth or if rollers don’t turn freely.
Structural inspection: Check all bolts, welds, and mounting points for cracks, looseness, or corrosion. Pay particular attention to:
Tighten loose bolts to specified torque. Flag any cracks for immediate repair (don’t operate with structural cracks).
Quarterly service is typically performed by a Gradeall service engineer or competent technician. This covers everything in daily, weekly, and monthly checks plus detailed system inspection.
Hydraulic system detailed inspection:
Electrical system testing:
Wire feed system refurbishment:
PLC and control system checks:
Wear part assessment: Quarterly service is when you assess wear parts and plan replacements:
Document all wear part conditions in the service report. This creates a maintenance history that predicts future replacement needs.
Annual overhaul is the most comprehensive maintenance event. This is typically scheduled during a facility shutdown or low-demand period.
Complete hydraulic seal replacement: All hydraulic cylinder seals are replaced regardless of condition. Seals are wear items with predictable lifespan (2,000 to 3,000 operating hours typically). Replacing seals annually during scheduled maintenance is cheaper than emergency replacement when a seal fails catastrophically.
Seal kit includes:
Cost: £200 to £400 for a complete seal kit. Labour: 4 to 6 hours.
Electrical component testing and replacement: Annual electrical work includes:
Cost: £150 to £300 for electrical components. Labour: 2 to 3 hours.
Structural inspection and NDT: Annual inspection should include non-destructive testing (NDT) of critical welds and structural components. This typically uses magnetic particle inspection or dye penetrant testing to detect cracks not visible to naked eye.
Focus areas:
If cracks are found, assess severity. Hairline cracks under 5mm can often be dressed out and re-welded. Cracks exceeding 10mm or in critical locations may require structural repairs or component replacement.
Control system software updates: Gradeall periodically releases software updates for PLC controllers. These updates improve performance, add features, or fix bugs. Annual overhaul is the appropriate time to install software updates.
Updates are provided via USB stick or remote download (if remote monitoring is enabled). Installation takes 30 to 60 minutes and includes backup of current program before updating.
Hydraulic oil change: Full hydraulic oil change every 2,000 operating hours or annually, whichever comes first. At 8 hours per day, 250 days per year, that’s 2,000 hours annually.
Oil change procedure:
Oil cost: £750 to £1,250 (£3-£5 per litre in bulk). Labour: 2 to 3 hours. Total: £1,000 to £1,600.
Some operators try to save money by extending oil change intervals. This is false economy. Degraded oil accelerates wear on pumps, valves, and seals. The cost of premature hydraulic component failure (£2,000 to £8,000) far exceeds the annual oil change cost.
Understanding wear part lifespan helps you plan maintenance budgets and prevent surprises.
These are typical lifespans. Actual replacement timing depends on operating intensity, maintenance quality, and operating environment (dust, temperature extremes, and contamination all accelerate wear).
Hydraulic oil is the lifeblood of a tyre baler. Poor oil quality causes 70% to 80% of hydraulic system failures.
Correct oil specification:
Don’t use automotive hydraulic oil, brake fluid, or other substitutes. Industrial hydraulic oil is specifically formulated for high-pressure systems.
Contamination prevention: Contamination enters hydraulic systems three ways: built-in (manufacturing debris), ingressed (external dirt), and generated (internal wear particles).
To minimise contamination:
Oil condition monitoring: Check oil condition monthly. Pour a small sample into a clear glass jar and look for:
If oil shows any of these signs, change it immediately rather than waiting for scheduled change interval.
You have three maintenance approaches:
In-house maintenance (DIY): Your team performs all maintenance using Gradeall’s manuals and support. You purchase parts as needed and call engineers only for complex repairs.
Pros: Lowest cost, maximum control Cons: Requires skilled staff, parts inventory, and diagnostic tools
Ad-hoc service (pay-per-visit): You call Gradeall when something breaks or when you want scheduled maintenance. We quote each visit individually.
Pros: No ongoing commitment, you only pay when needed Cons: Higher per-visit cost (£120/hour engineer rate), slower response, less predictable budgeting
Service contract (preventive + reactive): Fixed annual fee covers quarterly preventive visits, priority callout, and discounted parts. Typical cost: 6% to 9% of equipment purchase price per year.
Pros: Predictable budget, priority service, less downtime, someone else tracks maintenance schedules Cons: Higher annual cost than DIY
For most operations, service contracts deliver best value. The premium over ad-hoc maintenance (typically 10% to 20%) is offset by reduced downtime, predictable costs, and peace of mind.
Proper documentation serves three purposes: tracks what’s been done, predicts future needs, and supports warranty claims.
What to record:
Formats: Paper logbook works fine for small operations. Larger facilities benefit from digital maintenance management systems (CMMS). Gradeall provides logbook templates and can integrate with your CMMS if you use one.
Retention: Keep maintenance records for the equipment’s entire lifespan plus 3 years after disposal. This supports warranty claims, insurance claims, and regulatory compliance. Records also transfer with the equipment if you sell it (documented maintenance history increases resale value by 30% to 40%).
Daily: 5-minute visual inspection. Weekly: 30 minutes (oil top-up, greasing). Monthly: 2 hours (filter change, safety checks). Quarterly: 4-6 hours (full system inspection). Annually: full day (overhaul, seal replacement, oil change). This schedule applies to typical operations (8 hours per day, 250 days per year). Higher intensity operations should increase frequency.
Daily, weekly, and monthly tasks can be performed by competent operators with basic training. Quarterly and annual services require mechanical and electrical skills (typically performed by qualified engineers). Gradeall provides training for customer maintenance teams if you want to keep more work in-house.
Short-term savings, long-term pain. Skipping scheduled maintenance increases breakdown frequency by 200% to 300%. Equipment lifespan drops from 15-20 years to 7-10 years. Hydraulic seals that cost £200 to replace during scheduled maintenance cause £3,000 to £5,000 of damage when they fail catastrophically. Penny wise, pound foolish.
Common wear items are inexpensive: hydraulic seals £200-£400, filters £25-£40, contactors £30-£80. Major components are expensive: hydraulic pumps £800-£1,500, motors £3,500-£5,500, PLCs £1,200-£2,000. Preventive maintenance focuses on replacing cheap wear parts before they damage expensive components.
For business-critical operations, yes. Service contracts cost 6-9% of equipment purchase price annually but provide predictable budgeting, priority callout, and reduced downtime. The premium over ad-hoc maintenance (10-20% higher cost) is offset by avoiding emergency callout charges (£400-£600 per visit) and preventing catastrophic failures.
2,000-3,000 operating hours typically. At 8 hours per day, 250 days per year, that’s 12-18 months. Actual lifespan depends on operating conditions (temperature, contamination, duty cycle). Replace seals annually during scheduled maintenance rather than waiting for failure. Emergency seal replacement costs 3x to 4x more due to callout charges and potential secondary damage.
Date, tasks performed, parts replaced, abnormalities observed, and next service due. Keep records for equipment lifespan plus 3 years. Records support warranty claims, insurance claims, and demonstrate PUWER compliance. Documented maintenance history increases resale value by 30-40% if you sell the equipment.
Yes. Gradeall’s warranty requires maintenance according to the schedule in the operating manual. If a failure is caused by inadequate maintenance (old degraded oil, worn seals, skipped filter changes), the warranty claim will be declined. Keep maintenance records to prove compliance.
Preventive maintenance extends tyre baler lifespan from 7-10 years (neglected equipment) to 15-20 years (properly maintained). The difference is systematic care: daily inspections, weekly greasing, monthly filter changes, quarterly full services, and annual overhauls.
Maintenance costs approximately £3,000 to £5,000 annually (parts, labour, and service contract) for a typical industrial baler. Compare this to the cost of premature equipment replacement (£40,000 to £60,000) or catastrophic hydraulic failure (£5,000 to £12,000 repairs plus days of downtime). Prevention is dramatically cheaper than cure.
The most important maintenance tasks are hydraulic oil management (change every 2,000 hours), seal replacement (annually or when pressure drops), and filter changes (every 500 hours). These three tasks prevent 80% of hydraulic failures.
Keep detailed maintenance records. Document every service, every part replaced, every abnormality observed. This information predicts future problems, supports warranty claims, and increases resale value significantly.
