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.
