Cold Weather Operation
Glow Plugs
Optional Glow Plugs are installed inside the air intake. In cold weather (low
temperatures below 40°F):
1. Rotate the Ignition Switch PAST the ON position to the GLOW PLUG
position and HOLD there for 20-40 seconds.
2. After 20-40 seconds, continue to rotate the switch to the START position.
3. Once the engine has started, let the switch go-it will return to the ON
position.
In extreme cold weather (below 20°F), 2 or 3 cycles of Glow Plug may be
necessary before the engine will start.
Block Heaters
Optional Block Heaters, (installed directly on the crankcase), are operated by
plugging them into an electrical outlet via an extension cord. The block heater is
NOT thermostatically controlled. Use only just prior to saw use. DO NOT leave
the saw unattended with block heater in operation and DO NOT use when low
temperatures are above 20°F.
CAUTION
§ Do not leave optional Block Heaters plugged in for extended
periods when temperatures may rise above 20°F. The oil could
“cook” inside the crankcase and damage to the engine could
result.
§ If the Water System is not drained when the saw is not in use and
temperatures fall below 32°F, damage may occur to optional water
pumps and/or oil coolers.
Draining the Water System
When low temperatures fall below 32°F:
1. If the saw is equipped with an optional Water Pump, open the drain petcock
on the pump and allow the pump to drain.
• With the engine running, turn the water pump switch on for a few
seconds to purge water remaining inside the pump body.
2. Tilt the saw up and back, to allow water to drain.
3. Tilt the saw forward, to allow water to drain again.
