Attach the Oil Tank Gasket [177]<177> to the Case [220]<220>, and then apply Turbine Oil 56
(Nippon Oil & Energy) to the O-ring P-5 [178]<178>.
Attach the Oil Tank Cover [176]<176> to the Case [220]<220> with the four Small Screws 4 x 12WS
[209]<209>, while carefully avoiding contact with the Filter Ass'y [211]<211> or the Fuel Pipe 3 x 5 x
60 [214]<214>. Because the assembly is completed at the maximum oil discharge position in this
procedure, loosen the Step Bolt A [180]<180> and adjust the Oil Pump Adjuster [217]<217> by turning
it about three-fourths to one complete rotation counterclockwise from the maximum oil discharge
position. After making this adjustment, be sure to retighten the Step Bolt A [180]<180>.
(3) Reassembling the chain bar 10 and the saw chain
Before attaching the Chain Bar 10 [226]<226>, attach the Case [220]<220> to the Main Pipe Comp.
[170]<170> according to the following procedure:
Loosen the Hex. Hole Bolt 5 x 22/S [190]<190> and the Hex. Hole Bolt 5 x 10 [198]<198> of the Case
[220]<220>, and then insert the Case [220]<220> into the Main Pipe Comp. [170]<170> until it
touches the end of the Main Pipe Comp. [170]<170> with the spline of the Drive Shaft [171]<171>
aligned with that of the Pinion [192]<192>. Align the screw hole of the Case [220]<220> with the
5.5-mm dia. hole of the Main Pipe Comp. [170]<170>, securely tighten the Hex. Hole Bolt 5 x 10
[198]<198> so as to prevent removal of the Case [220]<220> from the Main Pipe Comp. [170]<170>,
and then tighten the Hex. Hole Bolt 5 x 22/S [190]<190> to fix the Main Pipe Comp. [170]<170> and
the Case [220]<220> in place. Install the Chain Bar [226]<226> onto the Chain Bar Tightening Bolt
[222]<222>, then push it toward the Sprocket Comp., 3/8 [205]<205> as far as it will go. Make sure
that the boss of the Chain Tensioner [221]<221> fits into the hole of the Chain Bar [226]<226>.
NOTE: Slightly move the Chain Bar 10 [226]<226> back and forth and make sure the boss of the
Chain Tensioner [221]<221> fits into the hole of the Chain Bar 10 [226]<226> properly.
Confirm that the direction of the Saw Chain
[225]<225> is correct as shown in the figure,
and align the Saw Chain [225]<225> with the
Sprocket Comp., 3/8 [205]<205>. Guide the
chain drive links into the Chain Bar 10
[226]<226> groove all around. Install the Side
Cover Comp. [207]<207> onto the Chain Bar
Tightening Bolt [222]<222>. Then fix the Chain
Bar Clamp Nut [227]<227> temporarily. Raise
the end of the Chain Bar 10 [226]<226>, and
tighten the Saw Chain [225]<225> by turning
the Chain Tensioner [221]<221> clockwise.
