MAINTENANCE
WARNING:
To avoid serious personal injury, always stop
the engine and allow it to cool before cleaning or maintaining
the unit. Never perform cleaning or maintenance while the
unit is running. Disconnect the spark plug wire to prevent
the unit from starting accidentally.
WARNING:
Wear protective clothing and observe all
safety instructions to prevent serious personal injury.
MAINTENANCE SCHEDULE
Perform these required maintenance procedures at the frequency
stated in the table. These procedures should also be a part of any
seasonal tune-up.
NOTE: Some maintenance procedures may require special tools or
skills. If you are unsure about these procedures, take the unit to
an authorized service dealer. Call
1-855-971-1123 for more
information.
NOTE: Maintenance, replacement, or repair of the emission control
devices and system may be performed by an authorized service
dealer. Call

NOTE: Please read the California/EPA statement that came with the
unit for a complete listing of terms and coverage for the
emissions control devices, such as the spark arrestor, muffler,
carburetor, etc.
FREQUENCY
MAINTENANCE REQUIRED
Before each
use
• Check for loose screws, nuts or bolts
(tighten as needed)
• Check for damaged or worn parts*
• Check the saw chain sharpness. Refer to
Maintaining the Saw Chain.
• Check the chain tension (adjust as needed).
Refer to Adjusting the Chain Tension.
• Fill the chain oil reservoir (refill frequently).
Refer to Adding Bar and Chain Oil.
After each use
• Clean the unit and inspect decals. Refer to
Cleaning in the Cleaning and Storage
section.
Every 10 hours
• Clean the guide bar groove and oil
passages.
• Clean and re-oil the air filter. Refer to
Maintaining the Air Filter.
Every 25 hours
• Check the spark plug condition and gap.
Refer to Maintaining the Spark Plug.
ADDING BAR AND CHAIN OIL
The guide bar and saw chain require lubrication to minimize friction.
Never starve the guide bar and chain of lubricating oil. Running the
unit without enough oil will decrease cutting efficiency, shorten the
life of the saw chain, cause rapid dulling of the saw chain and
excessive wear to the guide bar from overheating. An insufficient
amount of lubricating oil is evidenced by smoke, guide bar
discoloration or pitch build-up.
Only use bar and chain oil that is formulated to perform over a wide
range of temperatures with no diluting required in the chain oil
reservoir. Do not use motor oil or any other petroleum-based oil. Do
not use dirty, used or contaminated oil. Damage may occur to the
guide bar or saw chain. Dispose of old oil according to federal, state
and local regulations.
Checking the Chain Oil Level
1.
Set the unit on a flat, level surface. Position the unit with the
chain oil cap facing up (Fig. 14).
2. Make sure that the chain oil reservoir is at least half full (Fig. 14).
If the oil level is too low, add bar and chain oil. Refer to Filling
the Chain Oil Reservoir.
WARNING:
Failure to fill the chain oil reservoir will cause
irreparable damage to the unit. Make sure the chain oil
reservoir is always filled. Always use bar and chain oil.
WARNING:
Oil constantly flows from the chain oil
reservoir to oil the saw chain. Check the chain oil level
frequently so that it does not drop below half full.
