How to Change Engine Oil
Be sure the engine is not operating and is located on a level
surface before checking or refilling oil. Engine should be warm
for easy removal of oil.
1. Detach spark plug wire and move away from spark plug. If
the engine uses a battery, disconnect at negative terminal.
2. Remove dipstick and carefully tip the engine toward the
dipstick side to empty oil from oil fill area. Empty oil into a
suitable oil container and dispose of oil properly. SEE FIGURE
8
3. Tip engine back onto a level surface and fill with appropriate
oil to the top of the marking on the dipstick (SEE FIGURE 9).
DO NOT OVERFILL. For proper oil capacity, see the engine
manufacturer's instructions.
4. Reinsert dipstick and tighten. SEE FIGURE 9
How to Replace the Trimmer Line on Standard Head
For the best performance, use a heavy gauge (0.155" diameter)
trimmer line. Cut the length of the trimmer line to 21.5". Use the
length guide, located on the shield, to make sure the trimmer
line is the correct length.
Do not allow the length of the lines to vary more than one inch.
This is important to make sure the trimmer head is balanced
and does not vibrate.
NOTE: To extend the life of the trimmer line, keep the
trimmer line moist. If not kept moist, the nylon trimmer
line will become dry and brittle. Keep extra trimmer line
in a can of water. The line will then stay flexible and easy
to change. A flexible line will also last much longer.
1. Stop the engine. Wait for all moving parts to stop.
2. Remove the worn trimmer line from the line retainer.
3. First, thread the ends of the new trimmer line through the
outside loops. SEE FIGURE 10
4. Next, take the ends of the line, cross over the line retainer,
and thread the ends through the center hold. SEE FIGURE
11
5. Then, check to make sure that the ends of the line are even.
