Cooling System - Echo SHC-225S Operator's Manual

MAINTENANCE
Parts Required:
Use only NGK BPM-8Y spark plug (BPMR-8Y in Canada) otherwise
severe engine damage may occur.
1. Remove spark plug and check for
fouling, worn and rounded center
electrode.
2. Clean the plug or replace with a new
one. DO NOT sand blast to clean.
Remaining sand will damage engine.
3. Adjust spark plug gap by bending
outer electrode.
4. Tighten spark plug to 150-170 kgf•cm (130-150 in•lbf).

Cooling System

Level 2.
Parts Required:
To maintain proper engine operating temperatures, cooling air must pass
freely through the cylinder fin area. This flow of air carries combustion
heat away from the engine.
Overheating and engine seizure can
occur when:
• Air intakes are blocked, preventing
cooling air from reaching the cylinder.
• Dust and grass build up on the outside
of the cylinder. This build up insulates
the engine and prevents the heat from
leaving.
Removal of cooling passage blockages or
cleaning of cooling fins is considered
"Normal Maintenance." Any failure
attributed to lack of maintenance is not
warranted.
