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 ßuid 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.

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.
