Gear Mesh
1. Setting the proper mesh between the spur and pinion gears
is important. Improper mesh can result in damage to the
spur and pinion gears, shorter run times and can make the
motor run hot.
2. Place the scrap paper between the pinion and spur gear.
Slide the motor forward so the pinion teeth mesh with the spur
gears with the piece of paper pinched "tight" between them.
3. Tighten the motor screws to hold the motor in place, and
slowly rotate the gears until the paper is pushed out from
between the gears.
4. Rock the spur gear back and forth with light pressure. The
gear should be able to move a small amount (about 1/4 of
the size of one of the gear teeth) without moving the pinion.
5. Re-check the mesh after every few runs.

Loosely install the cap.
Slowly compress the piston

moving the piston up and down to
bleed more oil until the cap is tight.
