PREPARATION FOR USE
Proper Use Of The Tool
Your new Angle Die Grinder is designed for grinding and
deburring operations in confined areas. This tool features
a rear exhaust to direct airflow away from the work area,
a built-in regulator for convenient speed control and a lock-off
lever to prevent accidental starts.
Work Stations
Your Angle Die Grinder 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 incorporat-
ing 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.
