MAINTENANCE INSTRUCTIONS
– BSS18H39W
Lubricate blade shaft bearings daily! Note: When cutting dry grease blade shaft bearings two or
three times daily. Grease provides an added protective seal for the bearings. Use only premium
lithium-based grease conforming to NLGI No.2 consistency.
Every 40 hours of operation grease front axle pivot bearings and grease depth control
adjustment shaft.
Check engine oil daily. Keep oil clean and at proper level. Since the engine often operates at an
angle check the oil level (with engine horizontal) frequently to ensure that the oil level never
falls below the lower mark in the dipstick. Follow engine manufacturer's recommendation on
changing oil.
Clean engine air filter. When cutting dry clean air cleaner two or three times a day. See engine
manufactures manual for proper care and maintenance.
For engine care please consult the engine manual.
Blade shaft V-belts tension: This model concrete saw is equipped with premium V-belts. These
belts are properly tensioned at the factory. Severe damage or even breakage of the crankshaft
might occur if the belts are tensioned too tight. Check belt tension as set on the new saw and
never set belts beyond original factory tension. Not enough tension will result in poor saw
performance and short belt life. Belts should never be allowed to slip. After two hours of use, re-
tension the belts to make up for initial stretch.
To re-tension the belts:
1. Turn engine off.
2. Loosen the four bolts holding the engine.
3. Turn the horizontal tensioning bolt on the left rear of the saw frame clockwise until the
belts are tight.
4. Re-tighten the four bolts on the engine.
Continue to check the belt tension on a regular basis and re-tighten as necessary. To obtain
accurate V-belt setting a V-belt tension tester should be used. Check the setting on a single belt
of a matched set of V-belts. Apply load at the center of the belt span. Deflection should be 3/16"
with a 5 to 6 Ib. load.
Tighten fasteners regularly. Nuts and bolts may become loose particularly after the first few
hours of operation. On some models care must be taken to select the proper tools and
fasteners (Metric or English). Most are Metric however a few items use English or Inch
fasteners. Damage to the threaded fasteners could occur if incorrect tools or fasteners are
used.
