Maintenance

WARNING

To reduce the risk of serious injury always follow
the Pressure Relief Procedure on page 7,
before checking, adjusting, cleaning, or shutting
down the LineLazer.

CAUTION

For detailed engine maintenance and specifications,
refer to the separate HONDA engine manual.

Daily:

Check the engine oil level and fill as necessary.

Daily:

Check and fill the gas tank.

After the first 20 hours of operation and each 100
hours thereafter: Change the oil.

Weekly:

Remove the air filter cover and clean the ele-

ment. In very dusty environments, check the filter daily.
Replace the element as needed. Replacement elements
can be purchased from your local HONDA dealer.

Check the level of the TSL in the displace-

ment pump packing nut. Fill the nut, if necessary. Keep
TSL in the nut to help lubricate the pump packings. See

Use a grease gun to grease the zerks (32) on

this unit. The grease purges pivot areas of paint buildup.

Use only a (NGK) BP6ES or BPR6ES

plug. Gap the plug to 0.025 to 0.030 in. (0.7 to 0.8 mm).
Always use a spark plug wrench.
