MAINTENANCE/SERVICE

3)Remove the rubber latches and slide the belt guard away from the engine/electric motor until it clears the catch mechanism. Remove the belt guard from the main frame. If the SURFACE GRINDER is equipped with a Propane converted engine, determine that the Propane cylinder valve is closed before uncoupling the hose. Clean the inside of the belt guard with an appropriate solvent. Check for signs of wear and damage.

CAUTION

Observe all applicable safety precautions for the solvent.

4)Check the belt tension using the spring scale or belt tension tool midway between the engine clutch pulley and the transmission pulley. Belt tension should measure approximately 0.22 inch at 3-1/4 to 4-3/8 lbs. measured force range. FIGURE 41. If tension is within specifications, proceed to Step 5. If tension is not within specifications, refer to INSTALLING A REPLACEMENT V-BELT for specific information

FIGURE 41

5)Belt alignment is checked with the straightedge. Place the straightedge squarely against the transmission pulley. Properly aligned pulleys should also place the straightedge squarely against the engine/motor pulley. Remove the straightedge and rotate the engine pulley 120 degrees. FIGURE 42. Recheck alignment with the straightedge. Repeat the process until the engine/motor pulley is rotated a full 360 degrees. Maximum allowable misalignment is + - 1/32 inch. If pulley alignment is not within specifications, refer to INSTALLING A REPLACEMENT V-BELT for specific information.

6)Install the belt guard to the main frame. Determine that all safety related decals affixed to the belt guard are fully readable. If any decal is not fully readable, replace with a factory approved, replacement part only.

7)If the SURFACE GRINDER is powered by an engine, reconnect the engine spark plug wire. If powered by an electric motor and the machine is to be used immediately, reconnect the extension cord or SURFACE GRINDER to the power source. Determine that the ON/OFF switch located on the operator handle is in the OFF position
