Assembly requirements
Warning: do not start saw engine until unit is properly prepared.
Your new chain saw will require adjustment of chain, filling the fuel tank with correct fuel
mixture and filling the oil tank with chain lubricating oil before the unit is ready for operation.
Read the entire user manual before attempting to operate your unit. Pay particular attention to
all safety precautions.
Your user manual is both a reference guide and handbook provided to furnish you with
general information to assemble, operate and maintain your saw.

Guide bar / saw chain / clutch cover installation
Warning: always wear protective gloves when handling chain.

To install the guide bar
To ensure the bar and chain receive oil, only use the original style bar with the oil passage
hole (A) as illustrated above. (fig. 3a)
Make sure the chain brake lever is pulled back into the disengaged position(fig. 3a)
Remove the bar retaining nut(s) (B). Remove the chain brake cover (C) by pulling straight
out, some force may be required. (fig. 3c).Remove yellow spacer before mounting the bar.
Place the slotted end of the guide bar over the bar bolt (F). Slide guide bar behind clutch
drum (G) until the guide bar stops (fig. 3d).
7.3.2
To install saw chain:
Always wear heavy duty gloves when handling saw chain or making saw chain adjustments.
Spread chain out in a loop with cutting edges (1) pointing clockwise (fig. 4a).
Slip the chain around the sprocket (B) behind the clutch (C). Make sure the links fit
between the sprocket teeth (fig. 4b).
Guide the drive links into the groove (D) and around the end of the bar (fig. 4b).
Note: the saw chain may droop slightly on the lower part of bar. This is
normal.
Pull guide bar forward until chain is snug. Ensure all drive links are in the bar groove.
Install the clutch cover making sure the tang is positioned in the lower hole in the guide
bar. Make sure the chain does not slip off of the bar. Install the bar retaining nut hand tight
and follow tension adjustment instructions in section saw chain tension adjustment.
Note: the guide bar retaining nuts are installed only hand tight at this point
because saw chain adjustment is required. Follow instructions in section
saw chain tension adjustment.

Saw chain tension adjustment
Proper tension of saw chain is extremely important and must be checked before starting, as
well as during any cutting operation.
Taking the time to make needed adjustments to the saw chain will result in improved cutting
performance and prolonged chain life.
