McCulloch 250 - INSTALLATION OF BAR AND CHAIN

INSTALLATION OF BAR AND CHAIN
The bar used on your chain saw fits between the clutch guard and
the bar mounting pad on the side of the fuel tank (figure 3). The
slot in the end of the bar slides over the two studs projecting from
the side of the bar mounting pad. The bar is secured on the bar
mounting pad by the clutch guard when the two mounting nuts are
tightened. Use care when installing the clutch guard, and be sure
that the stud on the bar adjusting nut is properly engaged with the
hole in the bar. Install the bar mounting nuts but do not tighten
them until the chain tension is adjusted. The bar is adjusted for
correct chain tension by turning the chain tension adjustment screw.
Turning the screw clockwise tightens the chain; turning the screw
counterclockwise loosens it. It will be necessary to loosen the bar
mounting nuts whenever you adjust chain tension and to re-tighten
them after the chain tension is correctly adjusted.
Before installing your new chain, soak it for at least five minutes
in clean SAE 30 motor oil. This will help to make your chain last
longer.
Follow these steps for correct installation of your bar and chain.
1. Remove the bar mounting nuts (figure 3) and the clutch guard.
2. Put the bar on the studs with the slot in the bar fitting over the
two studs.
3. Fit the center link tangs of your Oil-soaked chain into the
groove on the upper edge of your bar. Make sure the cutting edges
of the chain teeth point toward the nose or rounded end of your
bar (figure 4).
4.
Slide the engine (or rear) end of the chain over the sprocket
(the colored gear just back of the slotted end of your bar) and
around the sprocket so that it hangs down beneath your chain saw.
Make sure the center link tangs fit between the teeth of the
sprocket.
5. Replace the clutch guard and tighten the bar mounting nuts just
enough to hold the bar in place.
