Foreseen Use Of the Tool

This tool is primarily designed for use with 1/4" dia. shank
carbide burrs of hardened steel countersink cutters provided their
speed rating matches the speed of the tool.
This tool should not be fitted with cutting off wheels, bonded
abrasive mounted point grinding wheels, saw blades, drill bits,
etc. If there is any doubt about the correct use of this product
contact your supplier for advice.

Work Station

The tool should only be used as a hand held, hand operated tool.
It is always recommended that the tool is used when standing on
the solid floor. It can be used in other positions but before any
such use, the operator must be in a secure position having a firm
grip and footing and be aware of the extra safety precautions that
must be observed when using this tool.

Putting Into Service

Air Supply

Use a clean lubricated air supply that will
give a measured air pressure at the tool of
90 psi/6.3 bar when the tool is running
with the lever/trigger fully depressed. Use
recommended hose size and length. It is
recommended that the tool is connected to
the air supply as shown in figure 1. Do not
connect the tool to the air line system
without incorporating an easy to reach and

operate air shut off valve. The air supply should be lubricated. It
is strongly recommended that an air filter, regulator, lubricator
(FRL) is used as shown in Figure 1 as this will supply clean,
lubricated air at the correct pressure to the tool. Details of such
equipment can be obtained from your supplier. If such
equipment is not used then the tool should be lubricated by
shutting off the air supply to the tool, depressurising the line by
pressing the lever/trigger on the tool. Disconnect the air line and
pour into the intake bushing a teaspoonful (5ml) of a suitable
pneumatic motor lubricating oil preferably incorporating a rust
inhibitor. Reconnect tool to air supply and run tool slowly for a
few seconds to allow air to circulate the oil. If tool is used
frequently lubricate on daily basis and if tool starts to slow or lose
power.
It is recommended that the air pressure at the tool whilst the tool
is running is 90 psi/6.3 bar. The tool can run at lower and higher
pressure with the maximum permitted working air pressure of
100 psi/7.0 bar.

Operating

shank. Always match correctly the shank size to the collet size.

Select a suitable burr/cutter that has a free running speed higher
than the maximum running speed marked on the tool. Make
sure that the diameter of the shank exactly matches the diameter
of the collet mounted in the tool. The collet size available for this
tool is 1/4" dia (6.35 mm).
Never try to close a 1/4" diameter collet to secure a 6 mm

If uncertain, have parts measured by a competent person. Push
the shank as far as possible into the collet and tighten the collet
nut using the spanners provided on the collet nut and output
spindle. The shank of the mounted point may be pulled forward
from the maximum insertion length but always ensure a
minimum gripping length of 10 mm.
The cutting edge of the burr/cutter must be between the Shoe
Plate (44) and the Adjusting Bar (39). Set depth of cut by
screwing Adjusting Screw (35) to set roller height.
The cutter must be unchipped and in good condition especially
the shank. The fitting of the burr/cutter should be done by a
trained operator. When first starting the tool with a new cutter
the tool should not be near other persons and be held in a
protected area, i.e. under a bench and run for a few seconds.
This will protect personnel from possible effects of damage to the
cutter before it was fitted to the tool.
Always use eye protection and wear protective gloves if there are
sharp edges in the work area. The tool and the process can
create a noise level such that the use of ear protectors is advised.
If the process creates a dust then use a suitable breathing mask.
Check that the material being work will not cause harmful dust or
fumes. If this is so then special breathing masks may be
required. If the tool vibrates when first fitting burr/cutter or
during operation, remove from service immediately and correct
fault before continuing to use.
Do not apply excessive pressure as this will reduce the cutting
efficiency and apply light loads to allow the burr/cutter to cut.
Handle the tool with care. If the tool is dropped, carefully check
for damage, i.e. chipping and start for the first time as for fitting
a new cutter, i.e. under a bench.
Never exceed the maximum air pressure. If there is possibility
always use this tool with a pressure reducing valve fitted in the
supply line. Your supplier will advise of suitable equipment. This
tool is fitted with a speed regulator and the speed may be
reduced by rotating Air Regulator (4) with a suitable screwdriver.
When making speed checks always rotate the air regulator to the
position to give the highest maximum speed.

Dismantling & Assembly Instructions

Disconnect tool from air supply.
Using the spanners provided remove Collet (26) and Collet Nut
(27). Loosen Setscrew (31) and Capscrew (29). Slide out Motor
Housing (12) from Trimmer Housing (28).

Motor Assembly

Hold motor housing in soft jawed vice on flats provided. Using a
peg spanner remove Locking Nut (25) , Silencer (24) and motor
assembly complete with Spindle (23). Hold cylinder (19) tightly in
the hand and tap the rear end small diameter of the Rotor (16)
out of the Rear End Plate (14) and Bearing (13). Remove Cylinder
(19 and the 3 off Rotor Blades (15). Grip Rotor (16) tightly in soft
jawed vice and using a spanner on flats provided unscrew
Spindle (23). Tap or press out Rotor (16) , Bearing (22) and
Spacer (21) from Front End Plate (20). Using pliers remove Pins
(18) from Cylinder (19).
Using a wide blade screwdriver remove Throttle Valve Screw (1)
complete with O- Ring. Pull out Regulator (4) , O-ring (3) , Throttle
Valve Spring (5) , O-ring (6) and Throttle valve (7). Press out
Throttle Valve Bushing (8) if necessary. Press out Pin (10) and
remove Lever (9). Using a spanner remove Air Inlet (11).
Clean and examine parts for wear or damage and replace only
