MAINTENANCE (CONTINUED)
AFTER FIRST 100 HOURS OF OPERATION
1. Change engine oil and filter after 100 hours, then every 250 hours after that, following the
engine manufacturer’s recommendations.
2. Change the gear box oil on the blower; use ISO Grade 100 Extreme Pressure Gear Oil
if your ambient operating range is from 32° F to 90° F. If your ambient operating range is
above 90° F, use ISO Grade 150 Extreme Pressure Gear Oil. Change oil every 1000 hours
after that.
3. Change the gearbox oil on the rotary air valve using SAE 90W gear oil. Fill oil to the side
plug. Change every 1000 hours after that.
EVERY 3 MONTHS OR 3,000 MILES (4,800 KM)
1. Check and adjust trailer brakes.
2. Torque wheel lug nuts to 95 to 115 ft.-lb. (129 to 156 N•m).
3. Check tire condition.
EVERY 12 MONTHS OR 12,000 MILES (19,300 KM)
1. Inspect and repack wheel bearings.
2. Inspect trailer brake magnets, pads, drums, etc.
WINTER SHUTDOWN AND STORAGE
1. Blow all built-up material out of hopper, rotary air valve, transition and discharge pan.
Disconnect battery cables.
Lead-acid batteries contain sulfuric acid, which will
damage eyes or skin on contact. Always wear a face
shield to avoid getting acid in the eyes. If acid contacts the eyes, flush
immediately with clean water and get medical attention. Wear rubber gloves
and protective clothing to keep acid off skin. Lead-acid batteries produce
flammable and explosive gasses. Keep arcs, sparks, flames, and lighted tobacco away.
Battery posts, terminals, and related accessories contain lead and
lead compounds, chemicals known to cause cancer and
reproductive harm. Wash hands after handling.
2. Remove the inlet elbow to the blower air chamber, and coat internals of impeller cylinder
with a rust inhibitor, such as WD-40. Reconnect piping to prevent foreign debris from
entering blower chamber. Rotate the drive shaft three or four revolutions. Repeat this
process every month or as conditions may require.
3. Store machine inside if possible. If machine is being stored outside, protect machine from
the elements as best as possible.
