10.4  Engine faults

Fault

Possible cause

Remedy

Engine does

not start

Fuel tank empty

Refuel, bleed the fuel system

Fuel filter clogged, in winter

due to paraffin separation

Change the fuel filter, use

winter fuel

Fuel lines leaking

Check all line connections for

leaks and tighten the fittings,

bleed the fuel system

Battery not charged or not

connected

Tighten the terminal clamps

on the battery, check all cable

connections

Starter defective

Have examined by a spe-

cialist

Emergency stop push button

is locked

Unlock the emergency stop

switch

Moving parts overheating

because of a lack of lubrica-

tion

Check the engine oil level,

correct if necessary
Check the engine oil filter,

replace if necessary
Have the lubrication system

examined by a specialist

Poor starting

of engine or

engine works

irregularly

with poor

power

Battery power too low, ter-

minal clamps loose or oxi-

dized causing the starter to

turn too slowly

Check the battery charge

condition, clean the terminal

clamps, tighten and cover

them with acid-free grease

Fuel supply too low, fuel

system clogged by paraffin

separation during winter

Replacing the fuel filter
Check all line connections for

leaks and tighten the fittings,

bleed the fuel system
Use winter fuel in winter
