The gearbox lubricant should initially be
replaced after 50 hours of operation. Subsequently
the lubricant should be replaced at 1000-hour inter-
vals or yearly, whichever occurs first.

skid steer, relieve any residual back pressure in the
hoses and remove the motor from the gearbox by
removing two bolts as shown as shown in Figure

Raise the pavement saw so the cutting wheel is
free to rotate and turn the cutting wheel manually
until the drain plug of the gearbox is at the 6 o’clock
(lowest) position as shown in Figure 28. Remove

4.
Fill the gearbox with a funnel using 80-90W gear oil
with a rating of GL-5. The gearbox should contain
32 oz. of lubricant after refilling. To verify the proper
amount of lubricant has been filled, rotate the fill
hole on the gearbox to the 9 o’clock position. If the
lubricant appears at the base of the drain/fill hole,
the unit is filled to the proper level.
5.
Reinstall the drain plug and lower the pavement
saw.
