The Arrow Hammer is an hydraulic drop-hammer which
uses an hydraulic cylinder and cable actuator system to
lift a weight to a specied height and then release the
weight to gravity free fall. The machine controls allow
the lift and drop cycle to be repeated automatically. The
machine can move itself in the work area.
The Arrow Hammer is generally used in three applica-
tions:
• Breaking and demolition of concrete, rock, asphalt
or other hard materials by repeated hammer blows
to reduce the size of the materials to allow for easy
excavation and/or recovery.
• Cutting and sectioning asphalt or concrete areas into
smaller sections before excavation.
• Compaction by impact in conned areas.
1. Check and tighten all bolts and nuts.
2. Check for frayed hydraulic lines and cables.
3. Check cross slide bearing adjustment.
4. Check oil levels.
5. Check and adjust cable properly; hammer should
come within 8 to 10 inches from top of the mast at
maximum cylinder extension.
6. Check all sheaves and bearings for free movement.
7. Check to make sure cable is threaded properly.
Before starting operation, inspect the work area and
inspect the machine.
1. Conrm the area is clear of bystanders. Establish a
safety zone by keeping bystanders beyond a 100 foot
radius around the machine when operating.
2. Inspect the area to conrm there are no pipes, lines
or other objects just beneath the work area surface.
3. Remove or mark any obstacles to avoid in the work
area.
Inspect the Machine
1. Complete the Daily Inspection Checklist.
2. Inspect the machine to be sure it is in working order.
If the machine is damaged or not in working order,
do not operate until it has been repaired by a quali-
ed technician.
3. Check the machine fuel level.
Note: See MACHINE COMPONENTS and MA-
CHINE CONTROLS to identify the controls used to
operate the machine.
After completing the Pre-Operation Inspection, test the
seat switch and backup alarm to be sure they are func-
tioning properly.
Test the Seat Switch

b. Test again. If the machine moves when you test
again, contact the manufacturer.
5. Turn the key switch to the RUN position.
6. Slightly press the reverse travel pedal. The alarm
should sound.

safely and check the alarm electrical harness con-
nections.
