POLE SAW ASSEMBLY: ADDING BAR AND CHAIN
LUBRICANT
WARNING:
Make sure the bar lube reservoir
is always filled. Failure to fill the bar lube reservoir
will cause irreparable damage to the unit.
Only use bar and chain oil that is formulated to perform
over a wide range of temperatures with no diluting required
in the oil reservoir. Do not use motor oil or any other
petroleum-based oil.
NOTE: This pole saw comes from the factory with the
bar lube reservoir empty. Use the bottle of bar
and chain oil that is included with the unit.
1. Remove the bar lube reservoir cap (Fig. 8).
2. Carefully pour the bar and chain oil into the bar lube
reservoir until the reservoir is filled.
3. Replace the bar lube reservoir cap and tighten securely.
4. Wipe off excess oil.
5. The unit is ready for use.
NOTE: Because bar lube reservoirs are designed to keep
oil slowly flowing onto the chain, be sure to check
the oil level after every 15 minutes of operation
and refill the bar lube reservoir as needed. Also
see the Chain Lubrication instructions in the
Maintenance and Repair Instructions section.
NOTE: Do not use dirty, used or otherwise contaminated
oils. Damage may occur to the guide bar or chain.
NOTE: The bar lube reservoir can be filled to the lip of the
fill opening without damaging the unit.
IMPORTANT! Please dispose of oil properly. Consult your
local waste authority for information regarding
available disposal options.
EZ-LINK TM COUPLER ASSEMBLY
The EZ-Link TM coupler allows the unit to use various Add-
TM
Ons. Refer to The EZ-Link System.

Testing the EZ-Link Coupler Connection
After assembling an Add-On, always test the unit:
1. Start the motor. See Starting and Stopping Instructions.
2. Briefly engage and release the trigger.
3. Make sure the Add-On operates. If not, remove and reinstall the Add-On (and extension boom, if
used).
4. Repeat these instructions until the Add-On operates.
CONNECTING AND DISCONNECTING THE POWER SOURCE
Follow these instructions in order to avoid injury and to reduce the risk of electric shock or fire:
• Verify that the trigger is released and the motor is off before connecting or disconnecting the power
source. Refer to Starting and Stopping Instructions.
• Verify that the motor is off and the unit is disconnected from the power source before inspecting,
