4. Handling of pump
(Operation in cold districts in winter)
1. Before starting the engine
(1) When cold, the battery capacity drops considerably. Make it a rule to charge
it periodically.
(2) Slowly pull the rope of recoil starter to see whether the pump rotates or not.
○
If it does not rotate, pour warm water through the water suction inlet of
pump or thaw it in a warm room.
(3) Turn the vacuum pump belt by hand to see whether the vacuum pump
rotates or not.
○
If it does not rotate, blow warm air on the vacuum pump exterior or thaw it
in a warm room.
○
Never use a fire for thawing.
There is a fear of inflammation or explosion.
2. Starting the engine
(1) When cold, press the tickler for several seconds.
(2) Immediately after starting, the running may be poor. Idle the engine for 1-2
minutes until it warms up.
3. Treatment after discharging water
(1) Drain the pump. (See 4. Handling (operation method), 5. Draining.)
(2) Close the water suction inlet cap.
(3) Start the engine.
(4) Interconnect the pump drain cock and anti-freeze mixture vessel by a hose.
Pulling the water suction handle, open the drain cock of pump to aspire the
anti-freeze mixture.
(5) When anti-freeze mixture has come out from the exhaust pipe of the vacuum
pump, return the water suction handle and close the drain cock of pump.
(6) Fill the hoses, fixtures, etc. also with anti-freeze mixture.
○
Do not use alcohol or the like because it deteriorates the rubber seals.
