5.3.3. MONTHLY ROUTINE SERVICING
5.3.3.1. Hydraulic Oil
Allow the machine to stand
for at least 8 hours without operating the pump. This will allow water and other
impurities to separate out of the oil and settle to the bottom of the tank.
Disconnect the 3/4" pipe at the bottom of the pump side of the ball valve and block off to prevent oil leakage
from the system.
Open the ball valve at the bottom of the tank just enough to allow a gradual trickle of oil and drain fluid from the
tank into a transparent container, until clean oil flows. Under normal operating conditions, a maximum of 0.25
litres (1/2 pint) is usually sufficient to remove all impurities.
If the oil does not flow clear but has a cloudy appearance, it is usually an indication that water is present. If this
condition occurs, a complete oil change will be necessary.
5.3.3.2. Chassis Bolts
Check all bolts for tightness.
5.3.3.3. Slewing Ring Gear Teeth
Remove any dirt from between the gear teeth and lubricate.
Note:- If solvents or a high-pressure washer are used for cleaning, re-grease the slewing ring bearings.
5.3.3.4. Lubrication
Lubricate all
small pivots throughout the machine with any good quality medium grade oil. Special attention
should be given to the cage control lever pivots. DO NOT lubricate the main pivot pins.
5.3.3.5. Pivot Pin Security
Examine all pivot pins on booms, cylinders and levelling system and ensure that they are all positively secured
in position.
5.3.3.6. Drive Gearbox Oil Level
Check the gearbox oil level
with the machine on level ground and, if necessary, top-up with EP 90
