MAINTENANCE 

 

Maintain your Rotary Hammer. 

It is recommended that the general condition of any Rotary 

Hammer be examined before it is used. Keep your Rotary Hammer in good repair by adopting a 
program of conscientious repair and maintenance. Have necessary repairs made by qualified 
service personnel. 

 

•  The  grease  in  the  gearbox  will  require  replenishment  after  approximately  50  hours 

accumulative use. After this time add approximately 50 grams of the grease (supplied), into 
the  gearbox.  First  remove  the  cap  from  the  tool  by  using  the  pin  spanner  (supplied).  Once 
removed add the grease through this hole. Ensure the cap is secured back into position prior 
to operation. 

•    After each use, blow air through the tool housing to ensure it is free from all dust particles that 

may build up. Build up of dust particles may cause the tool to overheat and fail. 

•    If the housing of the tool requires cleaning do not use solvents but a moist soft cloth only. 

  Never let any liquid get inside the tool; never immerse any part of the tool into a liquid. 

•    When the carbon brushes wear out the tool will spark and/or stop. The brushes are a wearing 

component of the tool and should be replaced prior to the carbon wearing out fully. Brushes 
will wear out after many uses. Always replace both brushes at the same time. 

Note: 

The distributor is not responsible for any damage or injuries caused by the repair of the tool 

by an unauthorized person or by mishandling of the tool.
