clockwise.
When the blade reaches desired
depth, release index plunger.
4. During cutting do not exert excessive side
pressure on handles to steer. Use only enough
pressure to follow previously marked line.
5. Move the speed control handle forward until
desired speed is obtained allowing the blade to
cut and not climb out of cut or stall.
6. If the saw should stall for any reason raise the
blade completely and disengage transmission
before starting engine again.
7. When lowering the blade into a partially-made
cut, use extreme care to be certain the blade is
perfectly aligned within the cut before starting to
cut again. Do not force blade into material by
lowering blade to fast or by propelling too fast
while sawing.
AT FINISH OF CUT
1. On self-propelled models, move speed control
lever to neutral position.
2. Bring the blade out of the cut by pulling the
index plunger and turning handwheel counter-
clockwise. Raise blade high enough to clear the
pavement when maneuvering the saw.
3. Turn off water valve. If saw is equipped with the
optional electric water pump, make sure it is
turned off.
4. Close engine throttle to idle position. Let engine
cool down before stopping.
5.
Do not leave the saw until the blade and saw have
completely stopped.
MAINTENANCE INSTRUCTIONS
1. Lubricate the blade shaft bearings daily! If
cutting dry, lubricate blade shaft bearing two or
three times daily.
bearings, depth control shaft, etc.) should be
greased every 40 hours of operation. Use only
premium lithium-based grease conforming to
NLGI No. 2 consistency.
2. Check the engine oil daily. Keep oil clean and
at proper level. Since the engine often operates
at an angle, check the engine oil level (with the
engine horizontal) frequently to ensure that the
oil level never fails below the minimum mark on
the dip stick. Follow the engine manufacturer's
recommendations for changing oil.
3. Air filter. When cutting dry, clean two or three
times per day.
additional information.
4. Blade shaft V-belts tension: This model
concrete saw is equipped with 3VX premium V-
belts. These belts are properly tensioned at the
factory. Severe damage or even breakage of
the crankshaft might occur if the belts are
tensioned too tight. Check belt tension as set on
the new saw and never set belts beyond original
factory tension. Not enough tension will result in
poor saw performance and short belt life. Belts

should never be allowed to slip. After four hours
of use, re-tension belts to make up for initial
stretch. To re-tension the belts, turn the engine
off. Loosen the four bolts on the sides of the
engine base. Turn the vertical tensioning bolt on
the front of the engine base clockwise until the
belts are tight. Re-tighten the four bolts on the
engine base. Continue to check the belt tension
on a daily basis, and re-tension as necessary.
To obtain accurate V-belt setting, a V-belt
tension tester should be used. Check the setting
on a single belt of a matched set of V-belts.
Apply load on the center of the span. Deflection
should be 3/16" with a 5 to 6 lb. load.
5. Tighten fasteners regularly: Nuts and bolts
may become loose particularly after the first few
hours of operation. Most fasteners on this unit
are metric. Please use the correct tool
6. Engine care: See engine manual. Clean dust
and dirt from cooling fans, as required, to
provide adequate cooling.
MAINTENANCE OF TRANSMISSION DRIVE
1. Check hydrostatic transmission oil daily.

Do not use multiple viscosity oils.
operation occurs during hot weather, drain oil
and refill with an oil having a viscosity
equivalent to SAE 30 or SAE 40 with API
classification SE, CC, CD or better.
2. Loose chain drive: The chain drive will stretch
during normal operation. It can be tightened by
loosing the four transmission attaching bolts and
moving the transmission up in the slots of the
transmission platform. Do not over tighten
chain, but allow a slight amount of slack.
Lubricate chain with oil to reduce chain wear.
3. Hydrostatic transmission cooling fins: Do
not allow the fan or cooling fins of the
transmission to become covered, or clog with
dust or dirt. This will not allow proper cooling of
the transmission oil.
4. Drive wheels:
engage the rear wheels with sufficient pressure,
slippage may occur. To correct this, lengthen
the engagement linkage by loosening the two
