the housing above the trigger (item 4 above). When knob is pushed toward the
right, rotation is forward (clockwise). When pushed in from the right to the left
side, rotation is reversed (anticlockwise), and when in centre position, it is locked
in neutral and the trigger is blocked.
NEVER push the Forward/Reverse/Neutral Switch until the drive stops turning.

OPERATING INSTRUCTIONS
REMEMBER: Do not attempt to use your Impact Wrench until the battery is fully
charged and you have read all the instructions.
REMEMBER: This cordless wrench is always in an operating condition and does
not need to be connected to a power supply.
CAUTION:
• ALWAYS place the FORWARD/NEUTRAL/REVERSE switch to the central
(NEUTRAL) position when changing sockets or batteries, to avoid accidental
starting.
• Do Not expose either the wrench or charger to rain or water.
• Do not overcharge the battery as this could damage the battery cells.
• Do not force the wrench. If it is laboring, it is possible that the battery
power is low. If so, stop working and recharge the battery pack.
• To prolong the life of the batteries, do not use for extended periods of time - no
more than a 20 minutes. Using it to do heavy work when the battery is weak,
could damage the battery irrevocably.
A. LOOSENING A NUT
1. If you are changing a wheel, first jack up the vehicle according to the vehicles
handbook, and remove any wheel trim, then proceed as follows:
2. Select the appropriate socket and place firmly on the square drive of the
Wrench.
3. With the FORWARD/NEUTRAL/REVERSE switch in the FORWARD position, and
holding the wrench firmly in BOTH HANDS, pull the trigger fully. The nut will be
impacted repeatedly until it is loosened.
NOTE: If the wheel spins, when attempting to loosen a nut, get an assistant to hold
it, or block it in some way.
B. TIGHTENING A NUT
1. Start the nut by hand ensuring it is not cross threaded, then with the
appropriate socket installed on the wrench, place it on the nut.
2. With the FORWARD/NEUTRAL/REVERSE switch in the REVERSE position, and
holding the wrench firmly in BOTH HANDS, pull the trigger gently. You can vary
the spindle speed by modulating finger pressure on the trigger.
3. Run each nut up in turn until it is ‘nipped’ up only - do not tighten - do not fully
depress the trigger. When all nuts are nipped up, tighten progressively by
pulling the trigger fully and allowing the action to operate for 3 to 4 impacts
only to prevent overtightening.
4. ALWAYS finish tightening with a torque wrench or suitable spanner.
