Preparation For Use; Work Stations; Putting Into Service - DeWalt DWMT70785 Instruction Manual

PREPARATION FOR USE

Proper Use Of The Tool
Your new Air Hammer is designed for chipping, riveting and
scaling metal and stone. Use only approved accessories with the
air hammer. Do not use the tool for any other purpose than that
specified without consulting the manufacturer or the manufacturer's
authorized supplier. To do so may be dangerous. Never attempt to
modify the tool for other uses.

Work Stations

Your air hammer should only be used as a hand operated tool. It is
always recommended that the tool is used when standing with solid
footing. It can be used in other positions but before any such use, the
operator must be in a secure position having a firm grip and footing.

Putting Into Service

Air Supply
CAUTION: This air tool requires lubrication BEFORE initial use,
also before and after each additional use.
WARNING: Use a clean lubricated air supply that will give a
measured air pressure at the tool of 90 psi/6.2 bar when the tool is
running with the trigger fully depressed.
Use recommended hose size. It is recommended that the tool is
connected to the air supply as shown in figure A on page 11. Do
not connect the tool to the air line system without incorporating an
easy to reach and operate air shut off valve. The air supply should
be lubricated. It is strongly recommended that an air filter, regulator,
lubricator (Frl) is used as shown in figure A on page 11 as this
will supply clean, lubricated air at the correct pressure to the tool.
Details of such equipment can be obtained from your supplier. If
such equipment is not used then the tool should be lubricated by
shutting off the air supply to the tool and then depressurizing
the line by pressing the trigger on the tool. Disconnect the air
line and pour into the air inlet 1 teaspoon (5cc.) of a
suitable pneumatic motor lubricating oil, preferably incorporating
a rust inhibitor. Reconnect tool to air supply and run tool slowly for a
few seconds to allow air to circulate the oil.
Lubricate tool daily if used frequently, or when it starts to slow or
lose power.
Using An Air Chisel Hammer
WARNING:
1) Read all instructions before using this tool. All operators must
be fully trained in its use and aware of these safety rules.
2) Do not exceed the maximum working air pressure of
90 psi/6.2 bar.
3) Use personal safety equipment.
4) Use only compressed air at the recommended conditions.
5) If the tool appears to malfunction, remove from use

6) If the tool is used with a balancer or other support device,
ensure that it is fixed securely.
7) Always keep hands away from the working attachment fitted to
the tool.
8) The tool is not electrically insulated. Never use the tool if there
is any chance of it coming into contact with live electricity.
9) When using the tool, always adopt a firm footing and/or position
and grip the tool firmly to counteract any forces or reaction
forces that may be generated while using the tool.
10) Use only genuine Dewalt spare parts or parts which perform
equivalently. Do not make temporary or permanent repairs with
unauthorized parts.
11) Do not lock, tape, wire, etc., the on/off trigger in the run
position. The trigger must always be free to return to
the "off" position when it is released.

trigger to release air from the feed hose before fitting, adjusting
or removing the working attachment.
