7.5 Return Spring Adjustment
Disconnect the machine from the
power source (unplug).
The return spring is adjusted at the
factory and should not need further
adjustment. If adjustment is necessary:
Unplug the machine from the power
source.
Loosen two lock nuts (A, Fig 14)
approximately 6mm.

Firmly hold the coil spring cover (B).
Pull out the cover and rotate until the
pin (C) on the return spring plate
engages the next notch in the coil
spring cover. Turn the cover clockwise
to decrease tension and counter-
clockwise to increase tension.
Tighten two lock nuts (A). Do not over-
tighten. Nuts should not contact the
housing when tight.
7.6 Cross Laser Adjustment
The lasers are designed for use with
twist drill bits.
There will be shadowing with wider
tools, such as Forstner bits, therefore
use will be limited.
The two laser beams need to meet at
the drill centre (Fig 15).
Fig 15
The Laser Assembly has been
installed and pre-set at the factory.
To adjust, install a small drill bit and
rotate lasers (A, Fig 16) gently with a
set of pliers.
Loosen Screw (C) for adjustment.
ATTENTION:
Class 2 Laser
Do not stare into beam of laser
Do not view directly with optical
instruments
Do not point the laser beam at people
or animals.
Do not use the laser beam on highly
reflective materials. Reflected laser
light is dangerous.
A defective laser beamer may be
replaced only, not repaired.
