Mantis Pruner E System - Manual (Page 7)

1. Loosen mounting nut and adjust the chain tension by
turning the tensioner screw
2. Hold unit vertically, and tighten mounting nut
3. Move saw chain backwards on guide bar by hand. Saw
chain should move freely on guide bar if it is in proper
mesh with the sprocket. If saw chain is difficult to rotate or
binds on guide bar, it is too tight. Re-adjust if necessary.
Adjusting saw chain tension
1. Power pruning mechanism is equipped with the automatic
oiling system that can be adjusted in the field. The saw
chain bar, and chain are lubricated when chain rotates. The
pump is set at the factory to a minimum flow rate.
2. Remove oil fill cap and fill reservoir with a quality, low
viscosity guide bar and saw chain oil. Tighten the cap
securely.
3. After starting the motor, run the chain at medium speed
and check the saw chain. Very little visible oil on the saw
chain will provide sufficient lubrication.
4. The oil tank will provide about 40 min. of cutting time
(when set to a minimum flow rate). Refill the oil tank as
needed.
5. A temporary increase in oil flow is recommended when
cutting hardwood or wood showing a large amount of sap.
This will speed oil consumption, and require more frequent
oil tank refills.
6. To adjust oil pump to max, the control screw must be
pressed in slightly prior to turning. Failure to do so
could damage the pump or screw.
7. Wipe debris from around the oil fill cap prior to re-filling
the oil reservoir.
Lubricating the guide bar and chain
WARNING DANGER
IT IS VERY IMPORTANT TO MAINTAIN THE
PROPER CHAIN TENSION. RAPID WEAR OF THE
GUIDE BAR OR THE CHAIN COMING OFF EASILY
CAN BE CAUSED BY IMPROPER TENSION.
WARNING DANGER
NEVER FILL THE OIL TANK OR ADJUST THE OIL
FLOW WHILE MOTOR IS RUNNING.
DISCONNECT POWER CORD FROM THE
POWER SOURCE FIRST.
WARNING DANGER
THE OIL FLOW RATE ADJUSTING SCREW HAS 3
INCREMENTAL SETTINGS.
WARNING DANGER
TO PREVENT PLASTIC DETERIORATION, DO NOT
USE SYNTHETIC OR SILICONE BASED OIL.
WARNING – DANGER
BE SURE UNIT IS UNPLUGGED BEFORE
MAKING ANY ADJUSTMENTS.
