EMERGENCY LOWERING SAFETY & MAINTENANCE
•
When using the emergency lowering valve on the top or bottom ram, it is important to fully extend
the cylinder to fill the ram up with oil. There is a delay if it is the first time powering the cylinder
down because it has to fill up with oil. If the oil tank is overflowing, clean up the oil spillage im
-
mediately. The spillage is due to the tank being overfilled.
•
The emergency slew handle and the slew valve handle must be operated at the same time to
allow oil to circulate. When the hydraulic motor is turned, it becomes a pump leading to the oil
being moved elsewhere.
WHEELS
Check for damage to the tyre/tyres. Replace if tread pattern is worn below 3 mm. On machines with
sliding axle, increased wear will be noticed on the inside part of the tyre/tyres compared to the outside
part. It is important that correct tyre pressure is maintained at all times. The correct pressure is 3.8 bar
(55 PSI) and not what may be indicated on the tyre. Refer to the tyre pressure sticker fitted on the top
of the mudguard. Tyre size is
205/75R16.
Note
For full service and maintenance information on the running gear, contact Snorkel to request a copy of
the running gear OEM service handbook.
BRAKES
Check Bowden cable for damage - Replace if inner steel core is visible. Sticking brakes can be down
to seized cables. The inner steel wire must run freely inside the cable.
Adjust the brakes with the wheels removed. Remove the plastic bung in the back of the brake plate.
