MAINTENANCE

WARNING:

When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.

WARNING:

Always wear safety goggles or safety glasses with side shields during tool operation. If operation is dusty, also wear a dust mask.

WARNING:

Before inspecting, cleaning, or servicing the machine, shut off engine, wait for all moving parts to stop, and disconnect spark plug wire and move it away from spark plug. Failure to follow these instructions can result in serious personal injury or property damage.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, lubricant, grease, etc.

WARNING:

Do not at any time let brake fluids, gasoline, petroleum- based products, penetrating lubricants, etc., come in con- tact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury.

You can often make adjustments and repairs described here. For other repairs, have the trimmer serviced by an authorized service dealer.

NOTE: Only use the knob to tighten the bolt. The use of other tools may allow overtightening of the bolt, which could damage the string head.

NOTE: For the BC30, the gear head locking tool can be inserted through the slot in the flanged washer and gear head to help hold the string head still.

If removed, replace the spring into the string head and push down to seat.

Reinstall the spool. For the CS30, the spool should be placed so “This side out for curved shaft” is visible. For the SS30 and BC30, the spool should be placed so “This side out for straight shaft” is visible.

Replace the knob in the spool.

Replace the string head cover, aligning latches with openings in the string head. Press cover and string head together until both latches snap into openings securely.

Install string as described in the next section of this manual.
