GENERAL INFORMATION
Regular maintenance is the key to long equipment life and safe operation. Maintenance requirements
have been reduced to the absolute minimum. However, it is very important that these maintenance functions be
performed as described below.
1.
Park your prime mover on a level surface with this product properly attached.
2.
Place your prime mover's transmission in "Park" and engage the parking brake.
3.
Lower this product onto preplaced blocking.
4.
Shut off your prime mover's engine, remove the starter key, wait for all moving parts to come to a stop,
and relieve all pressure in the hydraulic lines (refer to your prime mover's operator's manual for
instructions on how to relieve hydraulic pressure). On PTO drive models disconnect the driveline.
WARNING!
Do not use blocking made of concrete blocks, logs, buckets, barrels or any other
material that could suddenly collapse or shift positions. Do not use wood or steel
blocking that is warped, twisted, or tapered. Failure to obey this warning could result in
death or serious injury.
BEFORE EACH USE

On PTO drive models check driveline for wear.
•
Make sure that all nuts and bolts are in place and properly tightened.
•
Make sure that all other fasteners are in place and are performing their specified function.
•
Make sure that tires are inflated to maximum load pressure indicated on tire. Do not over inflate.
•
Make sure that all hydraulic fittings are tightened to specifications and that there are no leaks in any
fittings or hoses. (SEE THE HYDRAULIC CONNECTION SECTION).

FOR PTO DRIVE – AFTER 50 HOURS OF USE AND THEN EVERY 1000 HOURS OR ANNUALLY
•
Drain the 90 degree gearbox and the spur gear case of lubricant and refill with 80-90 W gear lube with

spur gear case.)
ANNUALLY
Repack the bearings in the wheels as described in steps 1-4 below.
1.
Make sure that there is no weight on the wheels. If the wheels are partially supporting the weight of this
product, restart your prime mover and move the loader and/or dump cylinders. Repeat the specified
shutdown procedure.
