(10 Hour Intervals)
1. Level the vehicle, place the travel
select lever in the (N) NEUTRAL
DETENT position and engage the parking brake switch.
2. Lower and retract the boom, level and lower the attachment to the ground,
transfer the transfer carriage to the rear position and shut off the engine.
3. Unlatch and open the engine cover.
4. Allow the hydraulic oil to cool.
5. Locate the sight glass (7) along the rear wall of the hydraulic tank. Check
the level of the hydraulic oil in the tank. The oil level should be in the center
of the sight glass when oil is cold. If oil is not visible, remove the hydraulic
oil fill cap (8) or (9) and add hydraulic oil (ISO Grade 46 Hydraulic Oil) until
the oil level is visible in the center of the sight glass. It is recommended that
the fill port (9) be used to add oil. The oil is added through the filter which
will help to prevent contaminates from entering the hydraulic system. DO
NOT overfill. DO NOT add oil through the hydraulic oil tank breather (10)
mounted on the engine side panel.
6. Reinstall the hydraulic oil fill cap (8) on the tank or the cap (9) on the fill
tube on top of the tank.
