Start engine and allow to idle while locating the auger in
position for drilling the hole. Push Engine Drill towards the wood
and increase the power by rotating rear handle anti (counter)
clockwise to drill the hole. For deep holes drill only 50 to 75mm
(2-3”) at a time and clear the auger frequently by pulling the drill
back into reverse gear, thus preventing overloading of auger in
the hole with wood chips.
Check 7 handle screws
#1- #7are tight as in
Figs 36 and 38 on page 6.
REACTIVE FORCES, TWISTING ACTION
Reactive (twisting) forces with the power drill may occur at
any time the auger is rotating. Reactive forces can be
dangerous! In any drilling machine, the powerful rotational
torque used to drill wood works against the operator. See
Fig.75 and 76. If the rotating auger is suddenly stopped by
contact with any binding object like a wood knot, split, nail or
cross hole, the reactive forces twisting the drill unit may occur
instantly.
!
SAFETY WARNING
Always stop the engine before putting
a Drill unit down or carrying it.
Carrying a drill unit by hand with the engine running is extremely
dangerous. Accidental acceleration of the engine can cause the
auger to rotate. Grip the front handle of the Drill when carrying,
with the auger behind you. During operation, the engine muffler
and the material around it reach extremely high temperatures.
Avoid touching the hot muffler, you could receive serious burns.
A worn, holes or damaged muffler could cause excessive heat to
be blown, damage (or a fire).
Transporting: Properly secure your Drill unit to prevent turning
over,
fuel spillage and damage to the Drill unit. Keep drill unit clean
at all times.
! WARNING
TRANSPORTING THE DRILL
! SAFETY WARNING
If Auger severly jams
in timber, stop engine,
disconnect Drill from auger and remove auger with a Stillsons wrench.
If motor stops while drilling for any reason then disconnect
drill from Auger and remove Auger with Stillsons. Rectify reason for
stoppage eg. ran out of fuel.
Never touch an auger with your
hand or any part of your body or
clothes when the engine is running, even when the auger
is not rotating. The auger continues to rotate for a short
period after the throttle trigger is released until the automatic
clutch disengages. The engine’s idling speed must always be
correctly ajusted, so that the auger does not rotate on idle.

These reactive twisting forces could
result in loss of control of the drill unit.
An understanding of the causes of these reactive (twisting) forces
will help you avoid loss of control.
The greater the force of the kickback reaction, the more difficult
it may become for the operator to control the drill reactive force.
! WARNING
! NOTE
WOOD AUGERS
Atom Brand Wood Augers have double cutting
front edges, better chip evacuation, excellent feed rate and easy
sharpening. See page 21 for sizes and sharpening.
! NOTE
The operator can stop or reduce the twisting of the
Drill by firmly holding the Front handle with his
left hand and twisting throttle control clockwise to the right with his
right hand causing the engine speed to slow to idle thus stopping
twisting of the drill and rotation of auger.
In an extreme situation when forward drilling and there is
insufficient time to counteract the twisting force which will cause
the drill to rotate suddenly to the left also will cause the rear hand
held throttle to move to idle position thus stopping the rotation of
the Drill unit. Pull unit carefully back into neutral increasing speed
and pull back hard for Drill to engage reverse gear and the auger
will un-screw out.
Recommence drilling and reversing to clear hole of wood chips
and continue drilling.
DRILLMASTER (including 4-Stroke Honda powered)
can be used sideways (as shown in Fig.77), to
reduce the handle reach when drilling at shoulder height. Any higher
and you must use a hydraulic bucket as in Fig. 74.
! NOTE
To clear the hole or withdraw the auger, allow engine to slow
down and pull attachment back towards you to engage reverse
gear and then increase engine speed. This will unscrew the auger
in an anticlockwise direction. The drill automatically changes
back to clockwise rotation.
Whenever Drillmaster is put into
reverse gear any re-active force DOES
NOT activate safety throttle control to idle speed. Therefore,
when reversing always be alert and have a firm grip on the unit.
! WARNING
FIG 77
If drilling higher than your shoulder height above
ground level, then you must stand only in a hydaulic bucket
(“cherry picker”). Anything else, such as standing on ladders,
tree branches, etc, is forbidden due to risk of injury. Fig. 74.
Over-reaching is dangerous.
