3. ASSEMBLING INSTRUCTIONS

UNPACKING FROM DOBLE STACK

1. Remove the saw and all components from its shipping crate. You will see:

Preassembled Saw with no Blade, unless diamond blade was purchased

separately and asked to be installed before shipping.

If asked, you will find saws in double stack and handles attached separately.

Note: All installation hardware must be inserted into its respective location on the

saw, see parts explosion for more details.

2. If saw is shipped double stack, using appropriated equipment, hold the upper saw

from the frame, unbolt the upper saw from the supports, and bring the saw to the

ground and then proceed to bring the lower saw to the ground, using the same

appropriated equipment.

Warning: failure to use proper lifting equipment could cause

saw to fall and cause serious injury.

3. If saw is shipped regular, using appropriated equipment, bring the saw to the ground

from its shipping pallet.

4. Unbolt the handle control assembly, flip it over into the walk behind style, and

proceed to bolt again and torque to 60 ft.-lbs.

5. Bring the saw up using the crank lift and lock at the desired position and lock handle.

ARBOR OR ENGINE SHEAVE INSTALLATION/REMOVAL

1. Standard sheaves on this saw are of the QD design. To remove sheave, remove

belt guard and remove belts.

2. 3 remove (3) hex head cap screw from (position A) sheave bushing.

3. Install (3) caps screw in tapped holes in (position B) sheave bushing.

4. Tighten tree caps screw alternately and equally until sheaves loosens from

bushing.

5. Loosen set screw over keyway in bushing and remove sheave/bushing.

6. Wipe all parts clean before assembly. A light coat of grease can be applied to

engine shaft or arbor shaft. Do not place lubricants on tapered bore of sheaves,

tapered hub of Q.D. bushing or bolt threads.

7. To install sheaves, line up drilled holes in bushing with tapped holes in sheaves

and install cap screw.

8. Align bushing on arbor shaft with bushing on engine shaft and tighten set screw

over keyway.

9. Tighten (3) cap screw alternately and equally to 10 ft. lbs. of torque and inspect

alignment.

ENGINE

See engine owner´s manual maintenance schedule.

ARBOR SET UP

1. Set each belt-arbor tension for 1/4” deflection with a 6 lbs. load in middle of

belt span. Over tension or under tensioning belts will cause premature belt

failure.

To adjust belt tension, loosen hex nut or belt tension bolt (two places).

To increase belt tension, turn tension bolts clockwise.

To decrease belt tension, turn tension bolts counter clockwise.

After adjusting belts, make sure engine mount is level to saw frame. Secure

position of tension bolts by tightening hex nut (two places).

2. When replacing arbor shaft or pillow block bearings, always adjust bearings so

arbor shaft runs PARALELL to rear axle. Torque bearings bolts to 60 ft. lbs.

CLEAN AND INSPECT BLADE COLLARS EACH TIME BLADE IS INSTALLED.

REPLACE DAMAGED PARTS. TO REPLACE BLADE PIN, USE ARBOR PRESS

DO NOT USE A HAMMER.

LUBRICATION

1. Grease wheels (4), arbor shaft bearings (2) daily. Use high quality gun grease.

2. Check water system for cleaning. 2 to 5 gallons per minute is required to for wet

cutting. Use ¾” ID hose to feed water to saw.

BLADE

1. Clean blade collars before installing new blade; inspect all blades before

installing on saw. Ring test abrasive blades to make sure they are free from

cracks; do not use abrasive blades that have been damaged i.e. missing blotters

cracked or missing sections. Inspect diamonds blades to make sure they don’t

have missing segments or stress cracks.

2. Use only blades rates to operate arbor speed (3000 RPM). Use only proper size

blade guards on your saw.

SAW ROCK INSTALLATION

1. Place saw on flat surface

2. Locate set screw/jam nut over right end of rear axle.

3. Loosen jam nut.
