Guide Bar Maintenance; Troubleshooting - EarthWise CVPS43010 Owner's Manual

BEFORE USING: Fill oil well with new quality bar and chain oil.
Unused SAE30 weight motor oil may be substituted.
If you drop the product, carefully inspect it for damage. If the blade is
bent or cracked, handles broken or if you see any other condition that
may affect the product's operation, it must be repaired before putting
it back into use. Call our customer service help line at
1-800-313-5111 for assistance.
CAUTION: Do not at any time let brake fluids, gasoline, petroleum
based products, penetrating oils, etc., come in contact with plastic
parts. They contain chemicals that can damage, weaken or destroy
plastic.
Make sure the unit is detached from the power supply, then use only
mild soap and a damp cloth to clean the tool. Never let any liquid get
inside the tool; never immerse any part of the tool into a liquid.
IMPORTANT: To assure product SAFETY and RELIABILITY,
repairs, maintenance and adjustment should be performed by a
qualified individual using identical replacement parts only.
Ensure that the plastic bar covers are in place when storing.
For smooth and fast cutting, chain needs to be maintained properly.
The chain requires sharpening when the wood chips are small and
powdery, the chain must be forced through the wood during cutting,
or the chain cuts to one side. Refer to instructions earlier in this
manual for instructions on properly sharpening the chain.
LUBRICATION SYSTEM FOR POLE/CHAIN SAW
The chain is automatically lubricated.
Store the tool in a dry, clean area out of reach of children.
During extended periods of storage, ensure that the tool is protected
against corrosion and rust.

damage
Model CVPS43010
Use only new bar and chain oil or unused SAE 30 weight motor oil
may be substituted. Never use wasted oil, low quality oil, or
insufficient oil. This could damage the pump; the bar and the chain
which may result in serious personal injury.
Check oil level before each work session, refill if less than ¼ full.
If the lubrication system does not work properly, check if the oil filter
and all oil-ways are clean and free from obstructions. If it is still not
working, call our customer service help line at 1-800-313-5111 for
assistance.

GUIDE BAR MAINTENANCE

When the guide bar shows signs of wear, reverse it on the saw to
distribute the wear for maximum bar life. The bar should be cleaned
every day of use and checked for wear and damage.
Feathering or burring of the bar rails is a normal process of bar wear.
Such faults should be smoothed with a file as soon as they occur.
A bar with any of the following faults should be replaced.
- Wear inside the bar rails which permits the chain to lay over
side ways.
- Bent guide bar
- Cracked or broken rails
- Spread rails
In addition, guide bars with a sprocket at their tip must be lubricated
frequently with a grease syringe to extend the guide bar life. Using a
grease syringe, lubricate weekly in the lubricating hole.
Turn the guide bar and check that the lubrication holes and chain
groove are free from obstructions.
At the end of the season, or if the tool is not being used for longer than
a month, wipe over all metal surfaces with an oil impregnated cloth to
protect them from corrosion or spray with a fine coat of oil.
