If engine crankshaft/electric motor pulley alignment
needs to be adjusted, proceed as follows:
a) using the 7/16 inch wrench, remove the two 1/4 inch
diameter cap screws from the engine pulley bushing.
b) Insert the cap screws into the tapped holes in the
bushing flange. Tighten progressively until the bushing
disengages from the pulley.
c) Insert the 1/4 inch diameter cap screws into the
tapped holes in the pulley. Tighten progressively until
the bushing applies tension to the pulley.
d) using the straightedge for reference alignment
purposes, tap the engine/electric motor pulley/bushing
into proper position.
e) Tighten the 1/4 inch diameter cap screws
progressively with the torque wrench to 95 inch
pounds. FIGuRE 33.

f) Recheck alignment as outlined per the beginning of
Step 8.
9) Apply increased belt tension by progressively
tightening the take-up cap screws against the engine
crankcase/electric motor thrust plate.
a) Recheck v-belt alignment.
b) Check belt tension with the spring scale or belt
tension tool midway between the engine/electric motor
and driveshaft pulleys. belt deflection should measure
approximately 3/16 inch (4.8 mm) at 3-7/8 to 5-1/2
pounds (1.8 to 2.5 kg) force. FIGuRE 34.
c) If belt tension and alignment is within specifications,
torque the engine/electric motor attachment cap screws
to 20 ft lbs (27 Nm.)
d) Recheck v-belt tension and alignment.
10) Install the belt guard to the main frame. Install the
flat washers and self-locking hexagon nuts. Torque
the nuts to 35 ft lbs (47 Nm.). Determine that all
safety related decals affixed to the belt guard are fully
readable. If any decal is not fully readable, replace with
a factory approved, replacement part only.

11) If the Surface Planer is powered by an engine,
reconnect the engine spark plug wire. If powered
by an electric motor and the machine is to be used
immediately, reconnect the extension cord or Surface
Planer to the power source. Determine that the oN/
oFF switch located on the operator handle is in the
oFF position.
