3. Place the chain over the rim sprocket and into the groove
on the guide bar. Make sure the cutting teeth edges are
facing forward on the top side of the guide bar.
CAUTION
・Always wear gloves when handling the Pruner
chain.
4. Pull the guide bar forward until the chain tensioner
adjustment pin hole is positioned over the chain tensioner
adjustment pin. If necessary, turn the chain tensioner
screw in the appropriate direction to align the pin with
the hole. Check that the drive links on the chain fit
correctly into the rim sprocket and guide bar groove.
5. Install the sprocket cover onto the two bar studs. Install
the bar stud nuts, but leave the nuts finger-tight).
6. Rotate the chain tensioner screw until all slack is
removed between the chain and the bottom of the guide
bar, but loose enough to allow you to pull the chain
around the guide bar by hand.
7. Tighten the bar stud nuts and recheck the chain tension.
IMPORTANT: When using a new chain, you must
check the chain tension frequently and adjust the ten-
sion as necessary until the chain breaks in. A correctly
adjusted chain gives optimum cutting performance and
prevents premature wear to both the chain and guide
bar.

Before Operation

Chain Oil

The chain and guide bar are lubricated by a centrifugal
pump. The oil discharge rate is controlled by the oil
discharge adjustment screw on the top of the pruner
head.
Remove the oil tank filler cap fill the tank, then replace
the cap.
IMPORTANT: Only use oil designed for lubricating
chain saw chains and guide bars. Do not use waste oil.
Never run the chain dry. In temperatures below
freezing, check the chain oil viscosity (pour point).
If the oil is not rated for use below freezing, it may not
provide adequate lubrication, resulting in damage to
the oil pump, chain and guide bar.
IMPORTANT: When filling the oil tank for the
first time, or when the tank is completely empty,
wait approximately 60-90 seconds before starting
the Pruner. This will give the oil time to flow from the
tank to the pump. Otherwise, an air lock can occur
which will prevent oil from moving through the pump.
This will result in damage to the chain and guide bar.
