MAINTENANCE AND SERVICE

Level check

Position the machine on a ßat surface. Clean the component before it is opened for reading or Þlling in order to prevent dirt entering the system. If the oil level is low, reÞll with the type and quality as per the ’Hydraulic ßuid and lubrication” table in the ’Technical data” section.

Hydraulic oil

•Manoeuvre the machine so the arm system’s cyl- inders are retracted and the outriggers are com- pletely folded.

•ReÞlling is needed if the level is more than one cm below the max mark.

Slew reduction gear unit

•Locate and loosen the dipstick. Wipe it clean, lower it and read off the level.

Drive motor, drive gear

•Manoeuvre the machine until one of the plugs is level with the middle of the hub and the other one is at the top position.

•Unscrew the level plug. The oil level should reach up to the hole.

Hammer lubrication

• Check that there is grease in the receptacle.

Wear and damage

General

NB! Deal with worn components as quickly as pos- sible. There is an increased risk of mechanical break- down if the machine is used despite damaged or worn components.

Wear of shafts and slide bearings

Bearings and any shafts necessary must be replaced in the event of play in joints and cylinder mountings. Replace or repair damaged components.

•If there is play in joints the bearings must always be replaced.

•Shafts must be replaced if they have wear damage. If there is wear damage on an expanding sleeve it indicates that it has not been sufÞciently tightened.

•Swing joints must be kept lubricated in order to be able to press out dirt that enters and to reduce wear on shafts and bearings.

Wear to rubber components

Check that caterpillar tracks and outrigger feet are intact. If they are so worn that the metal is visible they should be replaced.

Wear to hydraulic hoses

Do not use hoses that are distorted, worn or dam- aged. Make sure that the cords are not visible. Always have a spare hose on hand. Damaged hoses must be replaced immediately.

•Check that none of the hoses are rubbing against sharp edges. Be alert to the risk of abrasive jets.

•Adjust the length of hydraulic hoses so that they are never entirely stretched.

•Ensure that the hose is not twisted during mount- ing.

•Avoid severe bends in the hose.

Hydraulic couplings

•Check that the couplings are not damaged. Dam- aged couplings can damage hoses with the result that they come off. Change damaged couplings immediately.

•The hydraulic couplings should be lubricated be- fore tightening to reduce friction.

Wear to electric cables

WARNING!

The power cable must be disconnected when electric cables are checked. Check that the cables’ insulating casings are not damaged. Change damaged cables immediately.
