PREOPERATION PROCEDURES
PREPARATION FOR INITIAL USE
The tool, as shipped, has no special unpacking or as-
sembly requirements prior to usage. Inspection to as-
sure the tool was not damaged in shipping and does not
contain packing debris is all that is required.
CHECK HYDRAULIC POWER SOURCE
1. Using a calibrated flowmeter and pressure gauge,
check that the hydraulic power source develops a
flow of 7–9 gpm/26–34 lpm at 1000–2000 psi/70–
140 bar for the 8 gpm models and 4–6 gpm at 1000–
2000 psi/70–140 bar for the 5 gpm models.
2. Make certain the hydraulic power source is equipped
with a relief valve set to open at 2100–2250 psi/145–
155 bar minimum.
3. Check that the hydraulic circuit matches the tool for
open-center (OC) operation.
CHECK TOOL
1. Make sure all tool accessories are correctly in-
stalled. Failure to install tool accessories properly
can result in damage to the tool or personal injury.
2. There should be no signs of leaks.
3. The tool should be clean, with all fittings and fasten-
ers tight.
CHECK TRIGGER MECHANISM
1. Check that the trigger operates smoothly and is free
to travel between the "ON" and "OFF" positions.
INSTALL 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 difficult 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 firmly on the surface to be broken.
4. Squeeze the trigger to start the chipping hammer.
Adequate down pressure is very important.
NOTE:
Partially depressing the trigger allows the tool to op-
erate 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 fluid at low engine speed. When using the nor-
mally recommended fluids, fluid temperature should be
at or above 50 °F/10 °C (400 ssu/82 centistokes) 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.
UNDERWATER MODEL
PREVENTATIVE MAINTENANCE
After each use, the movable portions of the tool that
were exposed to water should be flushed with a water
displacing oil such as WD40. Remove any remaining
water and debris as follows:
1. Turn the tool upside down (without the tool bit) and
spray oil throughout the inside of the chuck and re-
tainer including down inside the retainer spring, also
spray any of the exposed piston area to displace
any remaining water.
2. Spray oil into the On/Off valve trigger slot area.
3. Dip or spray the entire tool.
4. Cycle the tool hydraulically several times before
storing away.
