Outriggers and arm system
• Lubricate all joints and cylinder mountings.
• The inner tube of the telescopic arm has to be
lubricated. Operate the telescopic arm to its outer
end position. Apply grease to the arm’s sliding
surfaces.
Gear ring
The gear ring has separate grease nipples for bearings
and cogs. To ensure that the grease is evenly distrib-
uted it should be applied followed by rotation and then
applied again.
• Connect a grease gun and grease the nipples.
• Stand at a safe distance, start the machine, rotate
the upper part by 90° and then turn off the motor.
• Repeat three times so that the gear ring’s bearings
and cogs are lubricated in four places.
NB! If the instructions are not followed there is a high
risk of the gear ring’s seals being forced out. The gear
ring’s bearings are then open to dirt and the seals have
to be replaced.
MAINTENANCE AND SERVICE
Service review
WARNING!
Ensure that nobody starts the machine while
service is taking place. Turn off the motor when
the machine has been moved to the desired
location. Disconnect the power cable and place
it so that it cannot be connected by mistake.
Lubrication
The machine can be moved to a position to access all
grease nipples (see picture).
Do as follows:
• Clean the nipple before greasing.
• Replace broken or blocked nipples.
• Connect the grease gun and pump 3-5 strokes.
Use lubricating grease as per the “Hydraulic fl uid
and lubrication” table in the “Technical data” sec-
tion.
Make a habit of always applying lubrication in the
same order in order to more easily remember all lubri-
cation points.
