Parts and Service Manual
HYDRAULIC TANK BREATHER CAP
The hydraulic tank is a vented-type tank. The breather cap has an internal air filter that can
become clogged or, over time, can deteriorate. If the breather cap is faulty or improperly
installed, impurities can enter the hydraulic system which may cause component damage.
Extremely dirty conditions may require that the cap be inspected more often.
1. Remove and discard the hydraulic tank breather cap.
2. Install a new cap onto the tank.
HYDRAULIC OIL INSPECTION
Replacement or testing of the hydraulic oil is essential for good machine performance and
service life. Dirty oil may cause the machine to perform poorly and continued use may cause
component damage. Extremely dirty conditions may require oil changes to be performed more
often.
Before replacing the hydraulic oil, the oil may be tested by an oil distributor for specific levels
of contamination to verify that changing the oil is necessary.
Hydraulic oil should be tested yearly and replaced if it fails. If the hydraulic oil is not replaced
at the Annual Inspection, test the oil quarterly. Replace the oil when it fails the test.
NOTE: Perform this procedure with the platform in the stowed position.
1. Slide out the Component Tray.
2. Disconnect the battery pack from the machine
ELECTROCUTION / BURN HAZARD. CONTACT
WITH ELECTRICALLY CHARGED CIRCUITS COULD
RESULT IN DEATH OR SERIOUS INJURY.
REMOVE ALL RINGS, WATCHES
AND OTHER JEWELRY.
3. Tag and disconnect the hydraulic pump outlet
line and remove the line from the pump. Cap the fitting on the pump.
4. Loosen the bolts and remove the hydraulic power pack form the tray.
5. Open the oil plug of tank. Drain all of the oil into a suitable container.
6. Loosen and remove the bolts and separate the tank from the pump body, taking great
care not to damage the o-ring seal.
BODILY INJURY HAZARD. SPRAYING HYDRAULIC OIL CAN PENETRATE AND BURN SKIN.
LOOSEN HYDRAULIC CONNECTIONS VERY SLOWLY TO ALLOW THE OIL PRESSURE TO
DISSIPATE GRADUALLY. DO NOT ALLOW OIL TO SQUIRT OR SPRAY.
