OPERATING PROCEDURES
GENERAL
This tool is intended for use with 1/2” drive impact sockets for loosening
and tightening nuts and bolts.
To prolong the life of the tool, do not use it continuously for more than 20
minutes at a time.
If the tool shows signs of decreased power, stop and recharge the battery.
Using the tool to do heavy work when the battery is weak drains the battery
very quickly and can damage the battery.
To use the tool, first start the fastener on the thread by hand, making sure it
is not cross-threaded.
Choose a 1/2” drive socket of the correct size and mount it on the drive
shaft.
Place the socket over the fastener.
Use the variable speed only for starting.
Allow the tool to come up to full speed.
When you hear the sound of the impacts, stop after three or four. The
fastener is tight.
VARIABLE SPEED
You can vary the spindle rotation speed by modulating finger pressure on the
trigger.
ROTATION DIRECTION
Your tool is equipped with a 3-position Forward / Reverse / Stop Lock Switch
through the house above the trigger. When the knob is pushed toward the right,
the rotation is forward (clockwise). When pushed in from the right to the left side,
the rotation is reversed (counter-clockwise), and when in the center position, it is
locked into stop and the trigger is blocked. Do not push the rotation direction knob
until the drive stops turning.
BATTERY INDICATOR
Pressing the battery indicator button will display the level of charge remaining in
the battery. There are 3 levels of charges, red light is low, yellow light is medium,
and green light is high. When the battery indicator is showing a red light, the
battery should be removed and put on the charger after cooling.
LED WORKING LIGHT
The impact wrench has 3 LED lights to illuminate the work area and improve
vision when working in areas with insufficient light.
To turn the LED lights on and off depress the LED light switch.
MAINTENANCE
Keep the tool clean by using a soft damp (not wet) cloth. Do not use solvents
on the plastic parts.
Lubrication is not necessary. After long use, have an authorized service
center maintain and lubricate the tool.
To maintain the best performance of your rechargeable NiCd battery, protect
it from overheating, by overcharging and during storage. Occasionally charge
the battery for 6 hours. The battery may also benefit from a full discharge from
time to time.
