After refuelling, make sure fuel does not leak or exude from
around fuel pipe, fuel grommet or fuel tank cap.
In case of fuel leakage or exudation there is a danger of fire.
Stop using the machine immediately and request your ECHO
DEALER to inspect or replace.
Check plug gap. Correct gap is 0.6 mm to 0.7 mm.
Inspect electrode for wear.
Inspect insulator for oil or other deposits.
Replace plug if needed and tighten to 15 N•m - 17 N•m (150

1. Clean dirt from grease fitting.
2. Hold the product firmly and carefully pump grease in fitting.

past seals and cause damage. Apply 1 - 2 pumps of
grease every 15 - 20 hours of operation.
NOTE
Use good quality lithium multi grease.
