MUFFLER
Remove the muffler and clean excess carbon from the exhaust port or muffler inlet every
100 hours of operation. If you find corrosion on the muffler, replace it.
CYLINDER (ENGINE COOLING)
The engine is air cooled, and air must circulate freely around engine and over cooling fins
on cylinder head to prevent overheating.
Every 100 Operating hours, or once a year (more often if conditions require), clean fins
and external surfaces of engine of dust, dirt and oil deposits which can contribute to
improper cooling.
NOTE!
Do not operate engine with engine shroud or muffler guard removed as this will
cause overheating and engine damage.
ANGLE TRANSMISSION (Fig. 3-4)
Check the gear case grease level about every 50
hours of operation by removing the grease filler
plug on the side of the case.
If no grease can be seen on the flanks of the
gears, fill the transmission with a quality lithium
based multipurpose grease up to 3/4. Do not
completely fill the transmission.
BLADE
Wear protective gloves when handling or performing maintenance on the blade.
• Use a sharp blade. A dull blade is more likely to snag and thrust. Replace the fastening
nut if it is damaged and hard to tighten.
• When replacing blade, purchase one recommended by manufacturer, with a 25.4mm (1
inch) hole.
• When replacing blade, use appropriate tools.
• When cutting edges become dull, re-sharpen or file as shown in figure. Incorrect
sharpening may cause excessive vibration.
• Discard blades that are bent, warped, cracked, broken or damaged in any way.
