MESSAGE TO OPERATOR

Upon receiving you new unit, it is always exciting to “get going” and see its performance!

The “operator”, however, is the key to everything!

Every operator should read this safety and operation manual to be sure of safety instructions and proper
operating procedure. If the owner of this unit is different than the operator, his reading this manual will not
protect the user. As with any mechanical equipment, this equipment is very safe if used with care and
precaution--and very dangerous if used carelessly.

Performance is relative to the operators knowledge

of how to use the equipment!

BE A GOOD OPERATOR...
BE A SAFE OPERATOR!

INSTRUCTIONS TO THE CREW

Every Dosko machine is designed and manufactured with safety in mind. All Dosko machines are built with
the highest grades of steel and component parts available. Equipped with lockable hood and belt guard, safety
decals, and operating instructions on every machine provide minimum chance of an accident.

No matter how hard a manufacturer tries to design a safe machine; accidents can still happen. Normally,
accidents happen when people do not read the owner’s manual or ignore warning stickers. Don’t ever take the
machine for granted, this is when accidents can happen.

Listed are a safety procedure to keep in mind

when operating a safe machine.

Before starting the machine. Make sure the area has been secured to keep

bystanders at a positioned into a safe and restricted area. Follow safe working
area sticker as pictured on page 17. Check to see that all belt guards are in place
and that the infeed hopper is clear of any foreign objects.

Make sure to position the discharge chute into a safe and restricted area.

Discharged chips are moving at a high rate of speed and can cause property
damage and/or injuries to animals or pedestrians.

When operating this type of machine, never wear loose fitting clothing or gloves

that do not fit your hand snug. Loose fitting clothes can become entangled in the
machine’s moving parts.

Whenever feeding brush into chipper always stand to the curb side of the hopper

infeed table. Never stand directly in hopper opening. Limbs and chips can be
kicked back or thrown out of hopper.

Never push short branches, twigs, and leaves into the Chipper. When you are

feeding a longer branch simply toss the smaller pieces on top. The longer branch
will pull them into the chipper automatically.

“NEVER” reach into infeed hopper. If a feeding problem should occur shut the

machine down and solve the problem.

INSTRUCTIONS TO THE CREW (CONT’D)

Listed are a safety procedure to keep in mind

when operating a safe machine.

Whenever feeding limbs into chipper, feed butt end in first. This practice will

decrease the problem of limbs wedging or jamming in hopper.

Always keep chipper on level ground when unhooked from truck. Always block

both tires, front and view. Make sure rear stabilizer tube is down and locked to
keep chipper from tipping backwards. Chipper should always be sitting level
from front to back when unhooked from truck.

Replace all decals on the chipper that are missing or that may have become

unreadable. Make sure decals are replaced in there original locations.

Make sure to replace all nuts and bolts with the same grade and style used.

Check all chipper bolts and nuts to maintain proper torques. All bolts and nuts
should be checked every two weeks. Always tighten bolts to our recommended
torque.

After completing any type of maintenance on this machine, make sure you

removed all tools and wrenches. Start engine and run chipper disk at a low RPM
Listen for any type of metal against metal noise. If you should hear any foreign
noise, disengage clutch immediately, stop engine and solve problem. Re-start
and slowly bring engine to a full RPM this practice can prevent machine damage
or worse, severe personal injury.

30 HP Kubota: Bring engine throttle to 3,000 RPM, in order to engage Smart

Feed system.

KNIVES

How long can I go without changing the knives?

The knives on your Dosko Chipper are made from the highest grade of Chipper Steel, which is heat treated

and ground to a very sharp edge. Their life is simply relative to what they chip. They may dull the first day

or they may last for months. The knife life naturally depends on the amount of dirt and rocks that enters the

chipper. Sometimes trees will have nails or wire imbedded below the surface.

Why must the knives be checked daily?

Because...

a) Dull knives cause excessive fuel consumption.

b) Dull knives cause unnecessary stress and strain on the machine.

c) Dull knives produce poor quality chips.

d) Dull knives reduce production rate slowing the feed rate.

e) Dull knives actually wear further and faster.

The proper belt tension and sheave alignment is essential for trouble free performance and optimum production
of your chipper. If the sheaves are not loosened or moved the belts can be tightened by simply sliding the pump
bracket.

1) Loosen the 3 nuts.

2) Loosen jam nut on tension bolt.

3) Tighten tension bolt to tension the belt. Proper belt tension is 7 lbs deflection. Without a gage, pull the belt
fairly hard with fore finger mid span. The belt should pull out approximately 3/8 inch.

4) Re-tighten 3/8-16 nuts to 23 ft. lbs. torque.

5) Re-tighten tension nut.

BELT AND SHEAVE CARE

No matter how many times you hear it; proper belt tension and sheave alignment is vital to every brush chipper
success. Here are just a few problems that can occur when belts and sheave are not properly maintained or
cared for.

Loose Belt - a loose belt will slip and then glaze over.
Once this happens the belt will not transmit power to the
flywheel which can cause the chipper to clog. Loose
belts once glazed over, can cause excess sheave wear.

Good Sheave Worn Sheave

Over Tightened Belt - to much belt tension can

cause premature bearing wear. If the belts are over
tightened you can break the crank shaft of the engine
or ruin the clutch from to much side load. When the
belts are worn out from over tightening they will
only cause the sheaves to wear.

Misaligned Sheaves - when sheaves are not aligned
properly the belts will glaze very quickly and a
slipping will occur. Misaligned sheaves will cause
belt to bounce or vibrate causing damage to bearings,
clutch and metal stress on machine.

HYDRAULICS

Wipe top of tank

clean before

opening filler cap

1) Keep hydraulic oil level in tank within 2 inches of the top. Do not over fill.

2) Use a good grade anti-wear hydraulic fluid equivalent to ISO-32. Check with supplier for severe hot or
severe cold oil recommendation.

3) The spin-on type hydraulic filter must be changed after the first ten hours of use, this allows for the initial
system cleanout. Then the filter should be changed after every 250 hours of use.

4) The hydraulic pump is belt driven directly from the engine so that the system is continuously under pressure
when the engine is running. Keep the belt tight, see page 34.

5) The system pressure is set for 2500 psi. Do not raise the pressure relief beyond 2500 psi. This would
damage the motors. (Note: Pressure relief valve is preset at the factory. DO NOT ADJUST or alter the
factory setting.)

6) The safety control bar is connected to the direction control valve causing the feed roll to turn forward,
neutral or reverse.

7) The speed control valve is located next to the hydraulic tank.

8) Keep your hydraulic system clean. Replace oil yearly, thoroughly clean tank. Clean filter screen. Replace
oil immediately if it becomes contaminated.

SMART FEED

The SMART FEED system monitors the chipper shaft speed and automatically stops the feed roller before
clogging occurs. SMART FEED will increase bearing, belt, and clutch life while reducing engine stress.

Normal Operation

1) 30 HP Kubota: Bring the engine speed up slowly to operating speed of 3000 RPM. The feed roller will

not turn until the engine exceeds 2800 RPM, the feed roller will start automatically.

2) S

MART FEED is always on, and in operation. The feed rollers will not turn if the chipper is not turning

at proper speed.

3) S

MAGNETS

MART FEED may be by-passed by removing its fuse. By removing the fuse you can by-pass the SMART

FEED if a failure occurs. Chipping can continue; However the operator must monitor the material in
