11.MAINTENANCE SCHEDULE
1. Check all hardware after the first 5 hours of use, the follow the maintenance schedule.
Tighten loose nuts or screws and replace any cracked or broken parts.
2. Clean the machine frequently. DO NOT use aggressive cleaners (i.e. containing solvents).
DO NOT use high-pressure water jets, aggressive detergents or solutions and liquids with
a temperature exceeding 86°. Use a fluff-free cloth only. Use a cloth which may be lightly
moistened only for removing dust and dirt. Hard packed dirt can be removed with a soft
brush. DO NOT let any water/cleaning liquid/vapor penetrate into the electric motor,
connectors/plugs, switches, etc. Cover all apertures, holes in the housing, connectors or
plugs, etc., or seal them with adhesive tape. Use a soft, low-pressure water jet and a
brush to rinse dirt and crustations away. Be particularly careful when near hazardous
parts of the machine (e.g. switch, motor). Clean the motor and switches only by wiping
with a moist cloth.
3. Check oil daily. Change after 5 (five) hours of use and every 25 hours after first change.
Refer to engine manual for oil grades.
4. Grease arbor shaft (2) daily. Use high quality gun grease, Kendall “SHP High temp”.
5. Lubricate the blade adjustment rod after every 8 hours of use.
6. Check the spindle bolt for tightness periodically.
7. MAKE CERTAIN that the cutting head is aligned properly. Misalignment can adversely
affect blade life.
8. Clean air filter and foam pre-cleaner daily. More often if dry cutting. Always use foam
element pre-cleaner over paper cartridge. Never run engine with clogged or no air filter.
9. Re-check arbor belt tension after first 25 hours of operation. Set each belt for ¼”
deflection with a 6lb load in middle of belt span. Over tensioning or under tensioning
belts will cause premature belt fatigue. To adjust, loosen hex nut on belt tension bolt (2
places). To increase belt tension, turn tension bolts clockwise. To decrease belt tension,
turn tension bolts counter clockwise. After adjusting belts make sure engine mount
plate is LEVEL to frame. Secure position of tension bolts by tightening hex nuts.
10.Re-torque the Blade and collar hardware after the first 25 hours of usage.
11.Grease pivot bearings periodically.

BEARING LUBRICATION CARE
There are two (2) grease points for the BBS20-E (Electric Motors) and four (4) grease points
for the BBS20-GH (Gasoline Engine). Use only Premium Lithium 12 based Grease, conforming
to NLG1 Grade #1 consistency. Grease daily.
ADJUST BELT TENSION (GASOLINE POWERED SAWS)
1. Remove engine-to-jackshaft and jackshaft-to-blade
shaft belt guards.
2. Check for proper belt tension on jackshaft-to-blade
shaft belts and engine-to-jackshaft belts.
3. 4-5 lbs. of force applied to the mid-point between
jackshaft and blade shaft pulleys should deflect the
belt approximately 3/16" on a used belt.
4. 4-5 lbs. of force applied to the mid-point between
engine and jackshaft pulleys should deflect the belt
approximately 1/8".
To adjust engine-to-jackshaft belts only:
5. Loosen engine mounting bolts.
6. Adjust engine adjusting nuts to apply tension while
maintaining pulley and bet alignment. Check pulley
alignment and parallelism with a straight edge from
jackshaft pulley to engine pulley.
7. When proper belt tension and parallelism have been
achieved, tighten engine mounting bolts.
To adjust jackshaft-to-blade shaft belt:
If the jackshaft-to-blade shaft belt requires adjustment, also adjust the engine-to-
jackshaft belts.
8. Loosen the 4 jackshaft mounting bolts, the 4 engine mounting bolts, and the jackshaft
adjuster screw jam nuts (Loosen the mounting bolts to slide easily.)
9. Adjust jackshaft-to-blade shaft belt first. To increase tension, tighten adjuster on blade
shaft belt side. To help maintain belt parallelism, loosen the jackshaft adjuster screw on
the engine side the same number of turns that the blade shaft side adjuster screw was
tightened. Using a straight edge on the blade shaft pulley to the jackshaft pulley, check
for pulley alignment and belt parallelism.
