III. MAINTENANCE
B. Motor
The motors are specially designed for masonry sawing. It is totally enclosed and the sealed bearings
require no lubrication. The motor is equipped with thermal overload protection.
1. Periodically clean the dirt and sludge build-up from the motor fan housing and cooling fins.
2. If the motor becomes overheated, the protector shuts the motor off. Turn the motor switch to the
"OFF" and identify the cause of overheating.
Engine
1. Refer to the engine owner’s manual for complete maintenance.
a. Pre-cleaner: every 25 operating hours, more often in dusty or dirty conditions, wash and oil the
pre-cleaner.
b. Paper Element: Every 100 operating hours, more often under dusty or dirty conditions clean the
paper element.
c. Engine Oil: After the first month or 20 operating hours, change the oil, then every 6 months or
100 operating hours.
C. Blade Shaft Bearings
The blade shaft bearings are lubricated and should not require daily relubrication under normal
conditions. However, to assure long life the bearings do need to be relubricated periodically. The time
interval between greasing is dependent on the running speed and operating conditions. The following
chart covers most situations and can be used as a guide.
Temperature Cleanness Greasing Interval
Up To 150

Dirty 6 to 12 Months
Over 150

F
Dirty Daily to 2 Weeks
Any Temperature Very Dirty Daily to 2 Weeks
Any Temperature Extreme Conditions Daily to 2 Weeks
Note: Never operate saw without bearing cover in place.
For normal conditions the grease should conform to the NLGI grade two consistency and be free of
any chemical impurities such as free acid or free alkali, dust, rust, metal particles or abrasives. For
best results, the bearings should be relubricated while in operation.
Note: Due caution for personal safety must be observed when servicing rotating equipment.
The grease should be pumped in slowly until a slight bead forms around the seals. This bead, in
addition to acting as an indicator of adequate relubrication, provides additional protection against the
entry of foreign matter.
