INSTALL TOOL BIT
The CH1513101, CH1533101 and CH1553101 Chip-
ping Hammers accept standard .580 inch hex shank
oval collar tool bits.
TO INSTALL AN OVAL COLLAR TOOL BIT
1. Remove the solid retainer.
a. Grasp the loop of the retainer spring and pull it
from the retainer.
b. Slip the solid retainer off the chuck end.
2. Insert the tool bit into the solid retainer. The hex
shank must be toward the chuck end. Align the oval
collar with the oval slot in the chuck end of the solid
retainer.
3. Insert the tool hex shank into the chuck end to en-
gage the hex liner. Index the shank in the hex liner to
get the desired bit orientation to the chipper.
4. Slide the solid retainer on the chuck end, aligning the
retainer spring slot with the groove.
5. Install the retainer spring.
6. Connect the hoses to the tool and the hydraulic
power source.
NOTE:
The pressure increase in uncoupled hoses left
in the sun may result in making them diffi cult to
connect. When possible, connect the free ends of
operating hoses together.
OPERATING PROCEDURES
1. Observe all safety precautions.
2. Move the hydraulic circuit control valve to the “ON”
position.
3. Place the tool bit fi rmly on the surface to be broken.
4. Squeeze the trigger to start the chipping hammer.
Adequate down pressure is very important.
OPERATION
NOTE:
Partially depressing the trigger allows the tool to
operate at a slow speed, making it easy to start the
tool bit into the surface to be broken.
COLD WEATHER OPERATION
If the tool is to be used during cold weather, preheat
the hydraulic fl uid at low engine speed. When using
the normally recommended fl uids, fl uid temperature
should be at or above 50° F/10° C (400 ssu/82 centi-
stokes) before use.
STORAGE
1. Disconnect the tool from the hydraulic power source.
2. Remove the tool bit and spray the chuck area with
WD-40™ inside and out.
3. Wipe clean and store in a clean, dry place.
