Operating Your Unit - Partner P842 Instruction Manual

OPERATING YOUR UNIT

BEFORE STARTING ENGINE
WARNING
: Be sure to read the fuel
information in the safety rules before you be-
gin. If you do not understand the safety rules,
do not attempt to fuel your unit. Contact an
authorized service dealer.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri-
cation. Lubrication is provided by the auto-
matic oiler system when the oil tank is kept
filled. Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheating
shown by smoke coming from the chain and/
or discoloration of the bar. Only use Bar and
Chain Oil for bar and chain lubrication.
FUELING ENGINE
WARNING
: Remove fuel cap slowly
when refueling.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality 2-cycle air-cooled
engine oil designed to be mixed at a ratio of
40:1. A 40:1 ratio is obtained by mixing 0,125
liter of oil with 5 liters of unleaded gasoline. DO
NOT USE automotive or boat oil. These oils
will cause engine damage. When mixing fuel
follow the instructions printed on the container.
Always read and follow the safety rules relating
to fuel before fueling your unit.
IMPORTANT
Experience indicates that alcohol blended fuels
(called gasohol or using ethanol or methanol)
can attract moisture which leads to separation
and formation of acids during storage. Acidic
gas can damage the fuel system of an engine
while in storage. To avoid engine problems,
empty the fuel system before storage for 30
days or longer. Drain the gas tank, start the en-
gine and let it run until the fuel lines and carbu-
retor are empty. Use fresh fuel next season.
Never use engine or carburetor cleaner prod-
ucts in the fuel tank or permanent damage may
occur.
CHAIN BRAKE
Ensure chain brake is disengaged by pulling
the front hand guard back toward the front han-
dle as far as possible. The chain brake must be
disengaged before cutting with the saw.
WARNING
: The chain must not
move when the engine runs at idle speed. If
the chain moves at idle speed refer to CAR-
BURETOR ADJUSTMENT
manual. Avoid contact with the muffler. A hot
muffler can cause serious burns.
To stop the engine, move the ON/STOP
switch to the STOP position.
To start the engine, hold the saw firmly on
the ground as illustrated below. Make sure
the chain is free to turn without contacting
any object.
Use only 40 --- 45 cm of rope per pull.
Hold saw firmly while pulling starter rope.

IMPORTANT POINTS TO REMEMBER
When pulling the starter rope, do not use the full
extent of the rope as this can cause the rope to
break. Do not let starter rope snap back. Hold
the handle and let the rope rewind slowly.
For cold weather starting, start the unit at full
choke; allow the engine to warm up before
squeezing the throttle trigger.
NOTE
: Do not cut material with the choke/fast
idle lever at the FULL CHOKE position.
