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
with genuine replacement parts. Ensure that the faces of End Plates (14) and (20) are flat and free from burrs. Lap on a flat fine grade or abrasive paper if necessary. Lightly lubricate all parts with Shell Tellus R10 or equivalent. Lubricate bearings with a molybdenum based grease. Ensure that Pins (18) locate in End Plates (14) and (20).
Dismantling Trimmer Housing
Unscrew Nut (40) and remove Washers (11) and (42) and Shoe (43). Using a Phillips screwdriver remove Screws (33) and remove Shoe Plate (44). Screw out Adjust Screw (35) and remove Adjust Bar (39). Press out Pins (34) and remove Adjust Screw (35). Holding adjust Bar (39) in a vice, remove Screw (36) , Washer (37) and Ball Bearing (38). Reassemble in reverse order examining all parts for signs of wear or damage replacing any parts necessary. Lubricate all parts as necessary.
