GREASING PROCEDURE
Greasing interval: - every 3 hours.
During Greasing following steps need to be followed
1) Place the Breaker vertically (90 Degree with respect to the horizontal surface) with chisel firmly
pressed inside the front head.
Note:- Never ever place the rock breaker in horizontal position while greasing.
In case of rock breaker positioned horizontally, the grease shall pass through the passage
provided in front head, cylinder & head cap and shall reach the Breather. This shall result in
chocking of the Breather.
2) Pump the grease with grease gun through the nipple as per model given.
3) When the Breaker is equipped with a new chisel apply the grease first and then mount the same.
4) Insufficient lubrication to the chisel shortens the life of front cover, chisel pins and chisel.
5) Grade of grease: lithian EP2.

ROCK BREAKER BREATHER
Location : Air breather assembly is provided on the head cap.
Function / Purpose: The air breather allows free passage of air through it and sends to front head chamber
during the operation of rock breaker. The fresh air ejects dust particles outside of front head thereby
preventing contaminants to enter the Impact chamber.
Failure / chocking of Breather results in;
1) Piston - cylinder Scoring
2) Contamination of Hydraulic oil resulting in failure of Hydraulic pumps and motors.
Preventive Maintenance : Breather should be cleaned every 50 hrs of operation.

grease

HYDRAULIC OIL FLUSING PROCEDURE
When Required ?
1) Flushing needs to be carried out during installation of the New rock breaker.
2) Flushing needs to be carried out every time when Rock breaker is installed after removal of the
bucket.

8
FRONT HOSES INSTALLATION PROCEDURE
1. Close both stop valves
2. Mount breaker onto the excavator
3. Install both hoses on breaker to ensure no twisting at the crimp joint.
After using hand, you can use spanner with proper torque

WRONG RIGHT
4. Open both stop valves
5. Start the operation

THROUGH BOLTS TORQUING
1. Step-1: Apply 90 kgf-m to T/Bolt of the Breaker.
2. After giving 90 kgf-m torque to T/Bolt, rotate in degree (°) clock wise as per given step-2 to achieve
specified torque.
3. After torque -- Put indication mark on the T/Bolt nut and Head Cap so that the loosening of T/bolt
in due course can be checked through the Window in the Bracket assy.
