12. Troubleshooting guide
Case 1. Starting failure
CHECK PROBABLE CAUSES ACTION
fuel tank → incorrect fuel → drain it and use correct fuel
fuel filter → fuel filter is clogged → clean
carburetor adjustment screw → out of normal range → adjust to normal range
sparking (no spark)
→ spark plug is fouled/wet → clean/dry
→ plug gap is incorrect → correct (GAP: 0.6 to 0.7 mm)
spark plug → disconnected → retighten
Case 2. Engine starts but does not keep running/hard re-starting
CHECK PROBABLE CAUSES ACTION
fuel tank → incorrect fuel or staled fuel → drain it and use correct fuel
carburetor adjustment screw → out of normal range → adjust to normal range
muffler, cylinder (exhaust port)
→ carbon is built-up → wipe away
air cleaner → clogged with dust → wash
cylinder fin, fan cover → clogged with dust → clean
Case 3. No suction of water
CHECK PROBABLE CAUSES ACTION
self-suction port → insufficient self-sucking water in pump → top up with water(see Page 7)
hose, clump → loose connection of suction hose → tighten securely not to suck air
packing
→ faulty packing in suction hose connection → replace with proper one(ask for service)
hose
→ suction hose crack breakage → replace with proper one
hose, valve → folded discharge hose, closed valve → extend and stretch hose, open valve
Case 4. Discharge water flow rate too small
CHECK PROBABLE CAUSES ACTION
strainer → clogged suction strainer → cleaning of suction strainer
pump position → pump position too high from water level → lowering pump height to water level
water resource
→ too far or too high place to discharge → secure water resource near to discharge place
fuel
→ engine output too low → check fuel degrading, water ingress.
Replace if needed (see Page 7)
