Setting the torque
This tool is fitted with a collar to set the torque for tightening
screws. Large screws and hard workpiece materials require a
higher torque setting than small screws and soft workpiece
materials. The collar has a wide range of settings to suit your
application.
Turn the collar to the desired setting. If you do not yet
know the appropriate setting, proceed as follows:
- Set the collar to the lowest torque setting.
- Tighten the first screw.
- If the clutch ratchets before the desired result is achieved,
increase the collar setting and continue tightening the
screw. Repeat until you reach the correct setting. Use this
setting for the remaining screws.
Hints for optimum use
Drilling
Always apply a light pressure in a straight line with the
drill bit.
Just before the drill tip breaks through the other side of
the workpiece, decrease pressure on the tool.
Use a block of wood to back up workpieces that may splinter.
Use HSS drill bits when drilling in metal.
Use a lubricant when drilling metals other than cast iron
and brass.
Make an indentation using a centre punch at the centre of
the hole to be drilled in order to improve accuracy.
Screwdriving
Always use the correct type and size of screwdriver bit.
If screws are difficult to tighten, try applying a small
amount of washing liquid or soap as a lubricant.
Always hold the tool and screwdriver bit in a straight line
with the screw.
When screwing in wood, it is recommended to drill a pilot
hole with a depth equal to the length of the screw.
A pilot hole guides the screw and prevents splintering or
distortion of the wood. For the optimum size of the pilot
hole, refer to the table below.
6
When screwing in hardwood, also drill a clearance hole
with a depth equal to half the length of the screw. For the
optimum size of the clearance hole, refer to the table below.
