MAINTENANCE PROCEDURES

CHECK HYDRAULIC OIL LEVEL

Location:

Sight glass (B). Behind the rear panel.

To Check:

Move the machine to level ground.

Level the frame.

Completely retract the boom.

Position the forks level.

Lower the boom to the ground.

Oil should be visible 1/2 way in sight glass (B).

DAILY MAINTENANCE

5 - 6

CHECK TIRE FOR PROPER INFLATION

Location:

Wheel ends.

To Check:

With the valve stem (C) positioned to the top of
the tire, check the tire pressure with the tire cold
and a properly functioning air pressure gauge.

Setting:

50 PSI.

All tires require a calcium chloride ballast or an optional foam
fill to be operated safely. The loss of ballast can affect the
machine's stability and cause a rollover hazard, resulting in
damage, injury or death.
