MAINTENANCE
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.
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.
