9.3 VARIABLE SPEED TRIGGER – FIG. 7
When the trigger
is depressed, the drive will rotate
(provided the direction switch
is set in the forward or
reverse position). This trigger switch is electronic which
enables the user to vary the speed continuously.
–
The speed varies according to how far the trigger
switch is depressed.
–
The further it is depressed, the faster the drive
spindle will rotate.
–
The lighter it is depressed, the slower it will rotate.
Note:
It may be necessary to initially release fixings with
a hand tool prior to using the impact wrench.
Note:
Always tighten fixings to the correct torque as indicated by the manufacturer using a
calibrated torque wrench. Failure to do so may result in the fixing becoming damaged or
insufficiently tightened.
Note:
This product is equipped with an electric brake.
9.4 BELT CLIP – FIG. 8
The spring steel belt clip
is convenient for hanging
the drill temporarily. The clip can be installed on either
side of the tool.
To install the clip:
–
Locate the clip
in position and fasten with screw
supplied, take care to not overtighten and strip
the thread.
9.5 OPERATION
Proper fastening torque is determined by the kind of
fastening, the size of the fastening or the material or
workpiece.
–
It is advisable to perform a test operation to determine the proper fastening time for the
fastening you are using.
–
Hold the wrench in straight alignment to the fastening.
–
Depress the wrench and use for the required amount of time.
–
After fastening, always check the torque with an appropriate torque wrench.
Note:
Do not use this tool to install wheel nuts on wheels without a torque limiting device.
Doing so could result in galled or broken nuts.
Note:
Using a universal joint or extension bar may reduce the fastening force of the impact
wrench and require longer fastening time.
Note:
Using an impact wrench creates heat. The metal housing at the front of the wrench
will become hot. In certain circumstances, the force required to tighten or remove fixings
may cause the fixings themselves to become very hot! Wear suitable gloves to prevent burns.
