Before Operation; Chain Oil - Toro ProLine 53035 Operator's Manual

Always wear gloves when handling the
Pruner chain.
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 (Fig. 12).
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 (Figs. 11
and 12).
5. Install the sprocket cover onto the two bar studs.
Install the bar stud nuts, but leave the nuts
finger-tight (Fig. 13).
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
(Figs. 11 and 13).
7. Tighten the bar stud nuts and recheck the chain
tension (Fig. 13).
IMPORTANT: When using a new chain, you
must check the chain tension frequently and
adjust the tension 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 (Fig. 14).
Remove the oil tank filler cap, fill the tank, then
replace the cap (Fig. 14).
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.
