was set.
The tool is now set to duplicate that tightness. For future use, note
that specific setting.
6. When critical torque values are not required, turn nut or bolt until it fits
snugly, and then turn a further one quarter to one half a turn - slightly
more if gaskets are used between surfaces.
7. For additional power during disassembly work, turn the air line regulator to
its highest setting.
This tool is rated at 5/8" bolt size, and is downgraded for spring ‘U’ bolts, tie
bolts, long cap screws, double depth nuts, badly rusted conditions, and
spring loaded fasteners as these conditions absorb much of the impact
power.
8. Turn off the wrench as soon as the impact sound is heard.
IMPORTANT: Where the torque setting is critical, the final tightening of nuts or bolts,
must be by hand using a properly calibrated torque wrench.
LOOSENING A WHEEL NUT
1. Remove any wheel trim, before selecting the appropriate socket and
placing firmly on the square drive of the wrench.
2. With the FORWARD/NEUTRAL/REVERSE switch in the REVERSE running
position, and holding the wrench firmly in BOTH HANDS, pull the trigger. The
nut will be impacted repeatedly until it is loosened.
IMPORTANT!
Release
the trigger immediately the nut begins to loosen.
3. Jack up the vehicle according to the vehicles handbook so that the
wheel is clear of the ground, then proceed to fully undo the wheel nuts.
4. Soak rusted nuts in penetrating oil, and break rust seal before twisting off
with the wrench.
ENSURE THAT THE CORRECT SOCKET IS BEING USED FOR THE NUTS ON
YOUR PARTICULAR VEHICLE. AN INCORRECT SOCKET SIZE IS LIKELY TO
DAMAGE THE HEADS OF THE BOLTS/NUTS.
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 clockwise (FORWARD)
running position, and holding the wrench firmly in BOTH HANDS, pull the
trigger.
3. Run each nut up in turn until it is ‘nipped’ up only - do not tighten. 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.
