Release all pressure from the system before attempting to install, service, relocate or
performs any maintenance.
16. Keep all nuts, bolts and screws tight and ensure equipment is in safe working condition.
17. Do not put hands near or under moving parts.
18. Air Hose
It is not recommended to install a quick coupler between the hammer and leader (whip) hose.
Using fittings or air hoses which are too small can create a pressure drop and reduce the
power of the tool. For most of the hammers, using 9.525 mm (3/8") I.D. fittings with 6.35 mm
(I/4") NPT threads are recommended. For the others hammer, using 12.7 mm( 1/2") I.D. with
9.525 mm(3/8") NPT threads are recommended. Most compressors are shipped with a short,
6.35 mm ( 1/4") I.D. hose. For proper performance and more convenience, use a 9.525 mm
(3/8") I.D. hose. Hoses longer than 15.24 m (50 feet) should have a 12.7 mm (I/2") I.D.
Never carry a tool by the hose or pull the hose to move the tool or a compressor.
Keep hoses away from heat, oil and sharp edges. Replace any hose that is
damaged, weak or worn.
19. Storage
The scaling hammer must be lubricated before storing. Follow the air cylinder lubrication
instructions with an exception to step 4. Only run the scaling hammer for 2 to 3 seconds
instead of 20 to 30 seconds because more oil needs to remain in the scaling hammer when
storing.

3.Maintenance Instruction
1. Lubrication
Proper lubrication is the owner's responsibility. Failure to lubricate the air
tool. Properly will dramatically shorten the lire of the tool and will void the
warranty.
This drill requires lubrication before the initial use and before and after each
additional use.
2. Drill requires lubrication throughout the life of the tool and must be lubricated in two separate
areas：the air motor and the scaling mechanism. Follow the outlined procedures.
3. Air Motor Lubrication
The motor must be lubricated daily. An air motor cannot be oiled too often.
Disconnect the hammer from the air supply before lubricating.
1. Disconnect the scaler from the air supply.
2. Turn the hammer upside down.
3. Simultaneously (at the same time), pull the trigger and pour a teaspoon of oil in the air inlet.
Then, push the forward and reverse button in both directions.
After an air tool has been lubricated, oil will discharge through the exhaust port during the
first few seconds of operation. Thus, the exhaust port must be covered with a towel before
applying air pressure. Failure to cover the exhaust port can result in serious injury.
4. Connect the drill to the air supply and cover the exhaust port with a towel.
Run the drill in both the forward and reverse directions for 20 to 30 seconds. Oil will discharge
from the exhaust port when air pressure is applied.
5. Drill mechanism lubrication
The drill should be lubricated monthly.
5.

Disconnect the hammer from the air supply before lubricating.
1. Disconnect the drill from the air supply.
2. Remove the slotted screw Allen head screw from the oil porthole on the right side of the tool that
has "OIL" stamped below the hole for.
3. Put three teaspoons of air tool oil in the oil porthole. Replace the screw.
4. Reconnect the air supply to the hammer and run for 20 to 30 seconds.
Lubricate the entire scaling mechanism by rotating the tool upside down and sideways while
running the tool.
5. Remove the screw and hold the oil port hole over a suitable container to allow excess oil to
drain.
6. If the oil is dirty, repeat the procedure above until the oil comes out clear. Install the screw and
tighten. The residual oil remaining in the scaling mechanism chamber is all that is needed for
proper lubrication.

General Troubleshooting Guide
Symptom Possible Cause(s) Corrective Action
Tool runs slowly
or will not operate
1.Grit or gum in tool.
2.No oil in tool.
3.Low air pressure.
4.Air hose leaks.
5.Pressure drops.
6.Worn ball
bearing in

1.Flush the tool with air tool oil, gum solvent, or
an equal mixture of SAE # 10 motor oil and
kerosene. Lubricate the tool after cleaning.
2.Lubricate the tool according to the lubrication
instructions in this manual.
3.Adjust the compressor regulator to tool maximum
while the tool is running free.
4.Tighten and seal hose fittings if leaks are found.
5-1.Be sure the hose is the proper size.
Long hoses or tools using large volumes of
air may require a hose with an I.D. of 12.7
mm (1/2") or larger depending on the total
length of the hose.
5-2.Do not use a multiple number of hoses
connected together with quick connect
fittings.
This causes additional pressure drops and
reduces the tool power. Directly connect the
hoses together.
6.Remove and inspect bearing for rust, dirt and
grit or worn race. Clean and regress bearing
with bearing grease.
Moisture blowing
out of tool
1.Water in tank.
2.Water in the air
lines/hoses.
1.Drain tank. (See air compressor manual).
Oil tool and run until no water is evident.
Oil tool again and run 1-2 seconds.
2-1.Install a water separator/filter.
Note：Separators only work properly when the
air passing through the separator is cool Locate
the separator/filter as far as possible from the
compressor.
2-2.Install an air dryer.
