Adjusting The Torque; Drilling/Screwing - Westfalia 50 93 80 Instruction Manual

Adjusting the Torque

You can control the maximum torque applied to the drill bit with the torque
setting ring (2). Attention! The torque setting ring should only be operated
when the machine is not running; otherwise the machine may be damaged.
To set the drill to the lowest available
torque setting, twist the torque control
ring until the small arrow on the drill-
housing points to the "1" printed on the
torque control ring. In this position the
torque clutch will slip with light drilling
resistance.
The higher the number the arrow points
to on the torque control ring, the larger
the maximum torque that can be applied
before the torque clutch will slip.
To set the machine to maximum available
torque twist the torque control ring until the arrow points to the drill symbol. In
this position there is no slip in the torque clutch.
Select a lower torque for inserting or removing of screws to avoid damage the
work-piece. For drilling select a higher torque setting. First do a test on an item
which is not your final work-piece and adjust the desired torque accordingly
before you start the actual work.
Drilling
 Before starting to drill select a lower speed to avoid the bit slipping away
from the desired hole location. If the drill-hole is deep, the drill-bit may
become jammed in the hole. In this event a high torque could damage the
drill bit or the drill. If the bit becomes jammed, hold the machine firmly and
immediately release the On/Off trigger. Switch to counter clockwise rotation
and use a low rotation speed to remove the jammed drill bit more easily.
