PRE-OPERATION 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 owmeter and pressure gauge,
check that the hydraulic power source develops a
ow of 3–9 gpm/11–34 lpm at 1000–2000 psi/70–
140 bar.
2. Make certain the hydraulic power source is equipped
with a relief valve set to open at 2250 psi/155 bar
maximum.
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 ttings 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.
OPERATING PROCEDURES
1. Observe all safety precautions.
2. Place the tamper on the surface to be compacted.
3. Squeeze the trigger to start the tamper.
WARNING
The tamper will rise quickly when rst turned on. Do
not stand over or place any part of your body on top
of the tamper. Wear safety shoes.
NOTE:
Partially depressing the trigger allows the tool to
operate at a slow speed, making it easy to start the
tamper on the surface to compacted.
4. Guide the tamper using both hands. One on the On/
Off valve trigger and the other at the tapered section
at the end of the handle tube.
5. When back-lling a deep hole, compact (tamp) the
back-ll after a maximum of 6 inches/15 cm of mate-
rial is added to the hole. This will ensure maximum
compaction of the lled hole and minimize any set-
ting that may occur.
COLD WEATHER OPERATION
If the tool is to be used during cold weather, preheat the
hydraulic uid at low engine speed. When using the nor-
mally recommended uids, uid 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.
