ASSEMBLY
Installation of connective soft pipe:
Affix the soft rubber pipe to the connector of inlet pipe. Please
note it must be installed over the thread. Tighten it with clipper joint.
On the other end of the rubber pipe, a filter should be attached.
OPERATION
IMPORTANT:
• Before starting, remove self-suction plug and pour water in the
pump until water overflows. When filled, tighten the plug firmly.
• Fully tighten self-suction plug, suction hose and others
connections. If they are loose, air will enter into your pump,
which may hinder the pump’s operation.
STARTING:
• Press the primer pump repeatedly until there are no air bubbles
visible in the fuel discharge line. Then move the throttle lever to
the starting position.
NOTE: This is not necessary if the engine is warm.
• If the engine is cold, move the choke lever to the closed position , pull the recoil starter until
the engine sounds like it wants to run. Then move the choke lever to the open position , pull
the recoil starter until the engine starts
NOTE: This is not necessary if the engine is warm.
• After the engine has started, move the choke lever to the open
position. Allow the engine to warm up 2–3 minutes before using.
• Move the throttle lever to the fastest position and begin to work.
• When the pump is used in winter, screw off the drain cock under
the pump and draw off water thoroughly after stopping the
machine. This prevents the pump from being damaged by frozen
water.
• If the gap between impeller and the surface of flow guidance is
over 1/32 inch (1mm), it can continue to be used after adding an
adjustment shim on the shaft shoulder.
• When changing self-priming pump’s machinery seal, be sure to
apply adhesive between the seal and pump cover. Otherwise, a
heavy hit may break the seal during operation.
When changing machinery seal, install silent ring set in the pump
cover, install movable ring set in the engine output shaft. Be careful
not to force the ring set when installing to prevent breaking the grind
piece.
The fuel of the pump is a fuel/oil mixture (50:1 ratio).
Keep fire and other explosives and inflammables away from the pump. Operate the
pump on a level surface to prevent fuel from spilling.
Do not add fuel into fuel tank or crank case when the machine is running.
Exhaust gas contains poisonous carbon monoxide. Never use the machine without proper
ventilation, otherwise people and animals would be affected.
Do not touch muffler and muffler cover while the machine is running or had just been
