Installing Bar Guides

Adding the guides to your chainsaw bar isn’t tough, there’s a few important things to keep in mind when drilling the holes:

1.) Use a Straight Edge.
Because every bar has a curve to it, include the chain and measure up from a straight edge to avoid over-cutting with the jig. This will give you a tight joint. 

2.) Measure.
1st hole: 1.5″ inches from bucking dogs and 1.5″ in from a straight edge beneath the bar and chain.  
2nd hole: measure the distance from the first hole, center to center according to the width of log for the jig you are using. (See Chart Below) and 1.5″ in from the straight edge. 

3.) Center Punch.
Mark your spot and keep the bit from wandering.

4.) Drill Slow!
The hardened steel of the bar will break bits if drilled at normal speed. Take it slow and you’ll get through it just fine.
