SECTION 6 MAINTENANCE SCHEDULE
6.1 Schedule
Daily Maintenance:
1. Check level of hydraulic oil in the truck reservoir
and add oil if necessary.
2. Visually inspect all hoses and fittings for wear or
damage. Inspect for signs of hydraulic leaks.
3. Visually inspect for external damage or cracks.
4. Inspect lower hooks for proper clearance. Maximum
clearance is 3/32 of an inch.
Weekly 40 Hour Maintenance:
1. Inspect all hoses and fittings for wear or damage.
Inspect for hydraulic leaks.
2. Check for loose or missing bolts.
3. Check for foreign matter between the arm slides
and the body. Foreign matter may lead to uneven
arm movement or galling of the slides or body.
4. Check that arm and slides are clean and lubricated.
Keeping the arm slides greased with a multipur-
pose, polymer fortified grease such as DuBois
Chemical MPG-2 will prevent excess wear. “Gun
barrel” grease the insides of the body sections, wipe
off excess.
500 Hour Maintenance:
1. Inspect base and lower retainer for hairline cracks or
signs of structural failure, particularly at the welds.
6.2 Torque Specifications
The following torque values are to be used on all
fasteners unless otherwise specified.
Lubricated refers to fasteners in the “As Received”
condition, which is normally a light preservative oil
coating on unplated fasteners and no oil coating on
plated fasteners. No special steps are taken to add
further lubrication prior to assembly.
