Chipping hammer 

Operation and parts manual  

Product registration card 

Operation 

 

The  chipping  hammer  must 

be  properly  lubricated  before  operation.  See 
“Lubrication” section. 

 

Figure 1 

1. 

Install  chisel  (not  provided)  as  follows.  See 
Figure 2. 

2. 

Place screwdriver or other tool in triangular 
end of retainer spring, and pull spring out of 
groove.  

3. 

Slide  retainer  off  cylinder.  If  needed,  insert 
screwdriver  into  slot  and  use  as  wedge  to 
help loosen retainer. 

4. 

Lubricate  chisel  shank  with  grease.  Insert 
chisel  through  rear  of  retainer,  and  rotate 
chisel  as  needed  until  oval  collar  of  chisel 
falls into notch of retainer. 

5. 

Slide chisel and retainer onto cylinder. Chisel 
shank should be fully inserted into cylinder, 
and retainer slot should align with groove on 
cylinder. 

 

 

Figure 2 (chisel not provided) 

6. 

Install  spring  by  feeding  it  into  groove  until 
completely  installed.  If  needed,  spray 
lubricant  into  groove  to  facilitate  spring 
insertion. 

 

An  unsecured  tool  can 

be  ejected  from  the  cylinder  with  force, 
causing injury. Retainer and spring must 
be  properly  installed  before  using 
chipping hammer.

 

7. 

Remove protective cap from air inlet (Figure 
1). If an in-line oiler is not being used, add 4 
or 5 drops of air tool oil (not included) into the 
air inlet. 

8. 

Blow  out  air  line  to  remove  any  dirt  or 
moisture,  then  connect  air  supply  hose  to 
tool. Set air pressure to 90 psi. 

IMPORTANT:

  Connecting  a  quick-change 

coupling  directly  to  the  tool  is  not 
recommended,  as  vibration  may  cause  the 
connection to fail. Instead, add a leader hose 
and  install  any  quick-change  couplings 
farther down the line. 

9. 

Hold  chipping  hammer  firmly  with  both 
hands. Place end of tool in contact with work 
surface, and press trigger. Do not push too 
hard; allow tool to do the work.  

Note:  This  tool’s  chipping  rate  (blows  per 
minute) is intended for larger surfaces – do 
not  attempt  to  break  up  small  pieces  of 
concrete. 

10.  Release trigger to stop hammer. 

Important:

  DO  NOT  raise  air  pressure 

above  maximum  rating  for  this  chipping 
hammer. If tool is not accomplishing task at 
maximum air pressure and flow, use a larger 
tool or different means to achieve task.
