15. SERVICE INSTRUCTIONS
15.1 Greasing of the machine
Greasing of the machine is of utmost importance in order to prevent wear in joints. Most of
the joints are service free - however the pressure roller bearing of slewing on pedestal must
be greased in accordance with the maintenance schedule, with grease containing EP
(extreme pressure) additive. Outrigger bearings and articulation bearings in all hydraulic
cylinders must be greased in accordance with the maintenance schedule.
15.2 Handling of fuel and refueling
Check fuel level and refuel if necessary (1). Before
refueling check the engine and fuel type: petrol or diesel.
In petrol engine use fuel defined by the engine
manufacturer in the engine Operators Manual.
ATTENTION!
Ignition switch of the petrol engine (2)
must be in position 1 in order that the engine will start!
15.3 Hydraulic oil and oil filter change
Hydraulic return oil filter is located on top of the
hydraulic oil tank (no. 2) on the chassis.
Replace the filter by removing the filter cap and
replacing the filter cartridge. When changing
hydraulic oil, the oil can be removed with a suction
pump from the opening of breather cap (no 3), or
by opening the drain plug.
In both cases it is
important to clean the magnetic drain plug.
Hydraulic pressure filter cartridge ( no. 4) must be
changed always when return filter is changed.
Take off the filter bracket, lift up the filter, open
and replace the filter cartridge
15.4 Hydraulic oil level
Hydraulic oil level can be checked with the dipstick in the filler (no. 3). Oil level should be at
the upper mark in the dipstick when the booms are down on transport supports and
outriggers are down on the ground.
15.5 Battery check
In order to secure the starting and safe operation the battery must be checked regularly.
Inspect and clean battery terminals regularly. Check also condition and fastening of battery
cables and terminal insulators. Make sure that battery cables cannot chafe against any sharp
edges. Check also condition and fastening of battery disconnect switch and cables.
ATTENTION! Always clean the battery before opening the caps so that dirt cannot get
in the battery.
