Flexible Head Air Cut Off Tool
With its low weight design, comfort grip and 3-position flexi-head design, this cut off tool
from Laser Tools is the perfect addition to your tool box. Features an easy to use safety
lock off throttle lever, speed control, forward and reverse cutting wheel rotation, adjustable-
position rear exhaust, 0.7 horsepower rating, free speed 16,000 revolutions per minute, and
consumes 3.6 cubic-feet per minute at 90psi.
The 3-position flexi-head is quickly adjusted to 25° up or down from the standard straight
position by releasing the securing clamp and repositioning the head. As the cutting wheel
guard position can also be adjusted, this allows a very versatile range of cutting wheel angles
and positions to assist when access is difficult. The rear exhaust port is also adjustable
through 360° to further assist operator safety when access is difficult.

Safety Precautions
• Eye and face protection plus heavy work gloves and suitable work clothing must be used.
A cutting wheel that breaks can cause very serious injury. Never wear loose clothing or
jewellery that could be trapped by moving parts.
• Ensure that every user reads and understands these instructions.
• Dust hazard: a suitable-grade dust mask or respirator must be used for any dust-
generating operations, particularly on glassfibre substrates.
• Vibration hazard: exposure to vibration can cause damage to nerves and blood supply of
the hands and arms. If you experience numbness, tingling, pain or whitening of the skin in
fingers or hands, stop using the tool immediately.
• Noise hazard: unprotected exposure to high noise levels can cause hearing loss and
tinnitus (ringing or buzzing in the ears). Wear suitable ear protection as required by
occupational health and safety regulations.
• Do not attempt to remove or change a cutting wheel until the tool has been disconnected
from the compressed air supply.
• Correct cutting wheel mounting is necessary to prevent injury from broken wheels. Do not
use chipped or cracked cutting wheels.
• Cutting wheels should fit cleanly over the spindle to prevent stress at the hole. Do not use
any additional washers or spacers to mount the cutting wheel.
• Never use a cutting wheel that is marked and specified with a speed lower than the tool
speed.

Compressed Air Supply
Operation
The tool must be connected to a suitable, clean, dry and lubricated workshop air supply (refer
to Figure 2, this is the recommended workshop air supply procedure). It is recommended
that the air pressure measures 90psi at the tool while running free. Water in the air line will
damage the tool. Drain the air tank daily and drain any dryer/filter unit when necessary.
Lubrication:
For first use of the tool, add a few drops of high quality air tool oil to the tool air inlet (F). In
use, if an in-line oiler is not installed, add a few drops of high quality air tool oil daily, squirted
into the tool air inlet. Adequate lubrication will help to ensure long tool service life.
Note: after an air tool has been directly lubricated, oil will discharge through the exhaust port
during the first few seconds of operation. Cover the exhaust port (E) with a cloth to collect
this discharged oil.
When tool is not in use, disconnect from compressed air supply.
Regulating the speed:
Refer to Figure 1: the speed of the instrument is adjusted
by turning the speed control (C) towards LO or HI.
Cutting Wheel Direction: Forward or Reverse:
Refer to Figure 3: the cutting wheel direction (forward or
reverse) is set by turning the Forward/Reverse control (D)
to the left for forward, or to the right for reverse.

Fitting the Cutting Wheel
• First lock the tool spindle with the spindle lock key (Min Figure 1).
• Refer to Figure 4: remove the cutting wheel reverse lock screw (O) with the 4mm hex key
(Nin Figure 1). Note: this screw has a left-hand thread and is designed to lock the cutting
wheel securing nut (P) when the tool is being used in the reverse cutting direction.
• Now remove the cutting wheel securing nut (standard right-hand thread) with the cutting
wheel securing nut key (Lin Figure 1).
• The cutting wheel (K) is placed over the location washer (Q), then reassemble the securing
nut (P) and the reverse lock screw (O), making sure that they are tightly secured.
Flexible Head Adjustment
Refer to Figure 5: the 3-position flexi-head is quickly adjusted to 25° up or down from the
standard straight position by releasing the securing clamp (Gin Figure 1) and repositioning
the head.
Note: there are three positions only - 25° up or down from the standard straight position,
and the cutting head will click positively into each of the three positions. Do not adjust the
cutting head to less than 25°, as although the securing clamp may be closed, the cutting
head position will slip as the tool is being used, which may result in damage or injury.
When using the tool, take care not to exert excessive force; burning of the work piece or
obvious speed reduction indicates too much force being applied. Start up the tool away from
the work piece and set it down onto the area to be cut steadily and with care. Move in the
direction of the cut. When cutting is finished, lift the tool away from the work piece before
stopping the motor.
Always use the cutting wheel guard, and position it so that the guard faces the operator.
Before using, test the cutting wheel by briefly running under a barrier (under a heavy work
bench for example), to stop any possible broken wheel parts or debris.
