Disconnect the air line and pour into the hose adaptor a teaspoonful (Sml) of a suitable pneumatic motor lubricating oil preferably incorporating a rust inhibitor. Reconnect tool to air supply and ran tool stowty lor a few seconds to allow aif to circulate the oil. ff tooi is used frequently, iubricate on daiiy basis and if tooi starts to slow or lose power. Si is recommended that the air pressure at the tooi while the loot is «inning is SO 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. Make sure that the diameter of the shank exactly matches the diameter of the collet mounted in the grinder. There are two standard sizes of collet available for use with this grinder, i.e., 1. -1/4' Da, (0,260 Sns) (6.35 mm) 2.-6 mm Dia. (0,236 ins) Additional two metric sizes of collet are available for use with this grinder, i.e., 1.-6 mm (0.2363 in.) 2. -3 mm (0.1181 Щ CotetHaktef T = length ol mounted point Lg = gripping length Lo = overhang Figure 2. Gripping length of coitet and chuck «ways match correctly the shank size to the eoaet size, if uncertain, have parts measured by a competent parson. Push the shank as far as possible into the cotiei and tighten Ihe collet nut using the spanners provided on the coliet 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 shcwm in Figure 2. as To” and is called the overhang, The Information with respect to mounted point, permissible running Page No 2 speed and reduction In running speed due to an Increase in eveihang ts available from ¡he suppSerofifte mounted points. If the ifiwsase in averting for access reasons lakes the perniissfeie wining speed ol the mounted pomtbetow 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 fitted, the grinder shoyJd not be near other persons and be hetd in a protected area. i.e. under a bench, and ran for a few seconds. This wilt protect personnel from possible effects of damage to the mounted point of wheel Defers it is was fitted to the grinder i.e. wheel breakage. Always use sye protection and wear proiecfivs cfcves 8 there are sharp edges in the work area. The tod and the grinding process can create a noise levei such that the use of ear protectors is advised. If the grinding process creates a dust, then use a suitable breathing mask. Check that the material being worked will not cause harmful dust or fumes. If this Is so, then special breathing masks may be required. II the grinder vibrates when first fitting a mounted point or during operation, remove from service immediately and correct iaufl before continuing to use. Do not apply excessive pressure as this wiii reduce Si# cySsng efficiency and can twsrrf the shank of Ste mourned point causing vibration and the possibility of breakage. Apply light loads io allow (he wheel to cm. Handle the grinderwith care. If the grinder Is dropped, carefully check ■the mounted point for damage, i.e. cracks, chipping, and start for the first time as for fitting a new wheel, i.e. under a bench. Never exceed the maximum air pressure If there te this possibility, always use this grinder With a pressure reducing valve fitted in the supply line. Your supplier wilt advise of suitable equipment This grinder is fitted with a speed regulator and th« speed may bs reduced by rotating air regulator (S) with a sugabie sc.f
