MAINTENANCE
Slew Drive Gears.
The slew drive gear is designed to be largely maintenance free. However, we
recommend the gear teeth be greased on a monthly basis with a high pressure
grease. Additionally, the ring gear and gear box should be greased on a six
monthly basis. The grease nipple for the ring gear is on the top face of the slew
gear, set between the fixing bolts. It can be accessed by lifting one of the side
covers, and slewing the structure appropriately.
Grease
Nipple
The ring gear should be inspected on a six monthly basis for excessive play. It is
unlikely there will be any wear if the machine is maintained correctly.
Grease
Nipples
To check the gear, place a payload of approximately 80Kg in the platform. Elevate
the lower boom to approximately half way. Then gently elevate the top boom,
whilst observing the ring gear. Excessive wear will be observed by noticing more
than 0.5mm movement between the inner and outer bearing rings.
Checking Limit Switch Operation.
The limit switches require no maintenance, other than a visual inspection, on a pre
operation basis. This is an important check, to ensure the switch is not
mechanically damaged, and the roller is always in contact with the cam, when not
under load.
The switch operation can be simply checked, by observing the LED display when
deploying the stabilizers. As an outrigger foot touches the ground and becomes
loaded, the appropriate light will change to green. This indicates that the switch
contact has operated correctly.

If the LED displays green at any other time then the machine must not be operated,
until the fault is rectified.
