v-belts
This machine is equipped with two heavy duty V-belts which are tensioned properly at the factory. These must be re-
tensioned after the first half day of operation and periodically thereafter. Adjust to the original tension as set at the factory,
which is approximately 1/4 inch of defection of the center of the belt halfway between the pulley on the motor and the pulley
on the blade shaft.
To adjust belt tension, first remove the belt guard. With the belt guard removed, loosen
motor mount bolts. Loosen the lock nut and adjust set bolt on the motor tension adjuster
until the required belt tension is achieved.
Retighten the motor mounting bolts.
The two most common causes of misalignment are shown in the drawings.
a). the engine drive shaft and the blade shaft are not parallel.
b). the pulleys are not located properly on the shafts.

electrical system
A fuse protects the battery charging circuit. The fuse and the battery are the only user serviceable parts of the electrical system. a
short circuit or a battery connected in reverse polarity will blow the fuse. Refer to the Honda engine manual for the location and type
of fuse. The fuse on the Honda engine is located between the starter solenoid and the engine, and is rated at 30 amps.
If the fuse blows, determine the cause of the problem before resuming operations.
Caution
Check water level weekly. Add distilled water if necessary. Check terminal cables and remove any deposits. Remove the battery for
recharging and follow the instructions for recharging. Damage can result to the battery and electrical system if the battery is charged
or installed in reverse polarity. Make sure that the negative terminal is connected to ground.
Remove and install battery as per instructions in initial servicing section of this manual. Be careful not to contact metal while
loosening positive terminal with tools.
Observe all battery precautions as outlined in the Initial Servicing section of this manual.

Caution
depth control
water system
The depth control (raising screw) consists of a threaded rod which feeds into a steel nut. In order to keep the two parts working
smoothly it is necessary to keep the rod free from dirt and sludge as much as possible. Cleaning the threaded rod with a rag after
each use will prevent sludge from collecting in the tube assembly and protect the threads. It is a good practice to keep the raising
screw threads lubricated, as the slurry generated during cutting will cause premature thread wear.
Check and clean system periodically. Make sure all outlets in the blade guard spray bars are open. Clean if necessary. When storing
saw under freezing conditions it is recommended that the water lines be drained to prevent damage.

Never make adjustments to belts or pulleys while engine is running.
DO NOT OVER TENSION as damage to belts and bearings may occur. Belts that are too
loose may slip, resulting in short life and loss of power to the blade shaft. If any belts are
worn or damaged, replace the complete set.
The motor mounting plate must be maintained parallel to the frame. Make sure all lock
nuts are tightened and retighten the bracket bolts.
See parts list for further v- belt spec. information.
