VALVE CLEARANCE CHECK AND

ADJUSTMENT

Over time, normal engine operation leads to wear in the engine valve train which decreases generator output. To restore generator output, it is necessary to check and adjust the engine valve lash at regular intervals throughout the life of the engine. However, proper valve lash adjustments require specialized training and tools. Adjustment by persons unfamiliar with the procedure can cause damage to the engine not covered under warranty. Contact an authorized generator dealer for assistance in locating qualified service personnel.

CAUTION

•This adjustment should only be performed by trained personnel. If incorrect adjustments are made, the unit may fail to operate or operate inefficiently.

FUEL SYSTEM INSPECTION

Avoid explosive and potentially lethal fuel leaks by inspecting the complete generator fuel supply system at intervals no greater than those listed in the Maintenance Table on page 25. Visually inspect all hoses for cracks, splits, or brittleness and replace hoses that show these or other signs of wear. Check all connections for tightness and cracks, replacing any broken fittings or clamps. Check all connections for leaks, while the generator is running, using approved equipment and methods. DO NOT use a flame to check for leaks.

WARNING

•Extreme caution should be taken while performing general maintenance.

•Do not smoke when near the unit.

•Keep flames, sparks, pilot lights, arc-producing equipment, switches and all other sources of ignition well away. Keep a type ABC fire extinguisher handy.

•Do Not operate engine if smell of fuel is present or other explosive conditions exist.

•Do Not use a flame to check for leaks.
