1.2 General
The purpose of shank lubrication is to lubricate the rock drill’s rotation
mechanism and shank. Lubrication is carried out using a mixture of shank
lubrication oil and compressed air. Proper shank lubrication is essential.
Inadequate lubrication rapidly causes serious damage to the rock drill.
Following these instructions will significantly increase the safety, reliability
and operating life of the rig. Sandvik Service is always willing to provide
advice and help with any problems related to the rig.

4.1.1 General
The pump unit delivers oil to the rock drill along an inserted pipe.
Pressurized air is used for distributing the oil to the lubricating points. In a
recovering system, pressurized air is used for collecting the lubricating oil
into a separate receiver. The system is equipped with an oil level switch.

7.3 Bleeding
Bleeding of SLU TANK is based on gravity, and it is carried out by opening
the bleeding screw (4) (CT7) 1–2 turns and then waiting until the oil no
longer contains any bubbles. During the bleeding the diesel engine/power
pack must be stopped. When bleeding the PUMP (14), connect an extra
hose (04-JIC) from port L to a suitable reservoir, start the power pack and
put the rotation on. Open the bleeding screw (4) (CT7) 1/2 turn and the
bleeding screw (2) (CT4) 1 turn. Leave them open for about 1 minute.
Close the bleeding screw (4) (CT7). Wait until the oil no longer contains any
bubbles. Close the bleeding screw (2) (CT4). Remove the extra hose from
line L and connect the original hose to port L. Start the compressor. Switch
on the Booster switch (position 1) approx. for 10 minutes to make sure that
there is shank lube oil in the hose all the way to the rock drill and to make

sure that the rod side of the SLU pump is bled. After boosting remember to
switch off (position 0) the booster switch (9). Turn off the rotation and stop
the power pack.

2. Disconnect the end of the desired shank lubrication hose from the rock
drill.
3. Start the power pack (electric motor or diesel) and turn the air on.
4. Turn the boost switch on.
5. Keep the boost switched on, until oil comes out of the hose (drain it into
the overflow receptacle).
6. When system has bled, turn off the boost switch, and stop the
powerpack.
7. Re-connect the shank lubrication hose to the rock drill.
