Resumen del manual
It may also be used with steel rotary files and carbide burrs provided their speed rating matches or exceeds the speed of the grinder. This tool should not be fitted with cutting off wheels, saw blades, drill bits, etc. If there is any doubt about the correct use of this product contact your supplier for advice. Also, make sure that the shank size of the attachment to be driven marches the collet size fitted in the grinder and that the maximum allowed running speed of the attachment exceeds that marked on the grinder. There are special rules governing the use of bonded abrasive mounted point grinding wheels - for details see section “Operating". Work Stations The tool should only be used as a handheld, hand operated toot. It is always recommended that the tool is used when standing on a 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 grinding machines. Putting Into Service Air Supply Use a clean lubricated air supply that will give a measured air pressure at the tool of 90 p.s.i./6.2 bar when the tool Is running with the air regulator fully open. 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 f 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, depressurizing the line by opening the air regulator on the tool. Disconnect the air line and pour into the hose adaptor 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. tf 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 while the tool is running is 90 psi/6.2 bar. Operating Select a suitable mounted point that has a free running speed higher than the maximum running speed marked on the tool. Always match correctly the shank size to the collet size. 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 the output spindle. The shank of the mounted point may be pulled toward from the maximum insertion length, but always ensure a maximum gripping length of not less than 10mm - see Figure 2. Be aware that the allowed running speed of the mounted point Is lowered because of an increase in the length of the shank between the end of the collet and the body of the mounted point. This distance is shown in Figure 2. as “Lo" and Is called the overhang. Collet Holder Collet Nut Collet / Lg Lo 0S = diameter of mounted point = length of mounted point Lo = overhang Figure 2. S = • diameter of shank Lg = gripping length Gripping length of coilet and chuck The Information with respect to mounted point, permissible running speed and reduction in running speed due to an increase In overhang Is available from the supplier of the mounted points, tf the increase in overhang for access reasons takes the permissible running speed of the mounted point below the free running speed of the grinder, select a smaller diameter mounted point. The fitting of the mounted point should be done by a trained operator. When first starting the grinder with a new point or wheel Mounted Point Page No 2 5978 1/8" (3 mm) Pencil Air Die Grinder Ref.
