4DR® SNOW BLOWER
This is a high-powered machine, with moving parts operating with high energy. You must operate the machine safely. Unsafe
operation can create a number of hazards for you, as well as anyone else in the nearby area. Always take the following precautions
when using this machine:
Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and
themselves.
Always wear protective goggles or safety glasses with side shields while using the SNOW BLOWER to protect your eyes from
possible thrown debris.
Avoid wearing loose clothing or jewelry, which can catch on moving parts.
We recommend wearing gloves while using the SNOW BLOWER. Be sure your gloves fit properly and do not have loose cuffs
or drawstrings.
Wear shoes with non-slip treads when using your SNOW BLOWER. If you have safety shoes, we recommend wearing them.
Wear long pants while operating the SNOW BLOWER.
Use ear protectors or ear plugs rated for at least 20 dba to protect your hearing.
Keep bystanders at least 75 feet away from your work area at all times. Stop the engine when another person or pet
approaches.
Never overlook the hazards of electricity. Always follow these precautions:
Never open the Control Box cover. Never attempt any electrical repairs yourself. If in doubt, consult a qualified electrician,
visit our website at www.DRpower.com or contact DR Power Equipment for toll-free support at: 1-800-dr-owner (376-9637) for
help or information.
Never use an extension cord that is not rated for outdoor use.
Never connect the Cord to the Snow Blower if there is an electrical hazard present.
Never connect the Cord to the Snow Blower in wet conditions.
Never connect the Cord to the Snow Blower with a damaged extension cord.
Always grasp the electrical cord plug when unplugging the cord from the outlet; never pull the plug out by the cord. Make
sure your fingers do not touch the metal prongs when plugging or unplugging.
Never Start the Snow Blower unless the electrical cord is plugged into a properly grounded outlet, which supplies 110-120V
power, and is protected by a 15-amp circuit breaker.
Never tamper with safety devices. Check their proper operation regularly.
When using an extension cord, keep the connection between the Control Box and the extension cord well away from any
water.
Protecting Yourself and Those Around You
Safety for Children and Pets
Safety with Extension Cords
Tragic accidents can occur if the operator is not alert to the presence of children and pets. Children are often attracted to the
machine and the snow blowing activity.
Never assume that children will remain where you last saw them. Always follow these
precautions:
Keep children and pets at least 75 feet from the working area and ensure they are under the watchful care of a responsible
adult.
Be alert and turn the machine off if children or pets enter the work area.
Never allow children to operate the SNOW BLOWER.

CONTACT US AT www.DRpower.com 5
Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or
explosion. Never overlook the hazards of gasoline. Always follow these precautions:
Never run the engine in an enclosed area or without proper ventilation as the exhaust from the engine contains carbon
monoxide, which is an odorless, tasteless, and deadly poisonous gas.
Store all fuel and oil in containers specifically designed and approved for this purpose and keep away from heat and open
flame, and out of the reach of children.
Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.
Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely. Don't handle gasoline if you or
anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Reinstall the fuel tank Cap and
fuel container cap securely.
If you spill gasoline, do not attempt to start the engine. Move the machine away from the area of the spill and avoid creating
any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly
dispose of the waste.
Allow the engine to cool completely before storing in any enclosure. Never store a machine that has gas in the tank, or a fuel
container, near an open flame or spark such as a water heater, space heater, clothes dryer or furnace.
Never make adjustments or repairs with the engine running. Shut down the engine, disconnect the spark plug wire, keeping it
away from the spark plug to prevent accidental starting, wait 5 minutes before making adjustments or repairs.
Never tamper with the engine’s governor setting. The governor controls the maximum safe operation speed and protects the
engine. Over-speeding the engine is dangerous and will cause damage to the engine and to the other moving parts of the
machine. If required, see your authorized dealer for engine governor adjustments.
Keep combustible substances away from the engine when it is hot.
Never cover the machine while the muffler is still hot.
Do not operate the engine with the air cleaner or the carburetor air intake cover removed. Removal of such parts could create
a fire hazard. Do not use flammable solutions to clean the air filter.
The muffler and engine become very hot and can cause a severe burn; do not touch.
Never use an extension cord longer than 25 feet and smaller than 12 awg in diameter, or longer than 50 feet and smaller than
10 awg in diameter; the cord will produce a voltage drop that will prevent the starter from supplying full power and may cause
damage to the Starter or Control Box. Use of a smaller diameter (larger awg number) extension cord could result in melting o
f
the insulation or even create a fire.
Always keep the electrical cord and/or extension cord away from excessive heat, oil, and sharp objects.

4. Replace the Valve Stem Protective Cap when finished.
Adding Oil and Gasoline
Engine Oil 5W-30 or 0W-30: -13°F (-25°C) or higher
0W-30: -13°F (-25°C) or lower
Fuel Unleaded gasoline
Note: Use only the recommended high detergent engine oil. Other types of oil could cause problems operating your machine. Please refer
to your Engine Owner’s Manual for detailed oil information.
1. Position the machine so the Frame and Engine are level. Remove the Oil
Fill/Dipstick (Figure 25) and clean the end of it with a rag.
2. Machines are shipped with no oil. Initially add 3/4 of the oil recommended
by the Engine Manufacturer (see oil quantities in your Engine User
Manual). Wait one minute for the oil to settle.
3. Insert the Dipstick without screwing it in and check the oil level. Clean the
Dipstick with the rag after checking.
4. Continue adding a few ounces of oil at a time, rechecking the Dipstick until
the oil reaches the fill mark. Be careful not to overfill.
5. When full, replace the Dipstick and screw all the way down.
6. Remove the Gas Fill Cap and fill the Gas Tank with fresh, unleaded gas
(with a minimum of 85 Octane) to approximately 1" to 1-1/2" below the top
of the fill neck to allow for fuel expansion (Figure 25). Be careful not to
overfill and ensure you reinstall the Gas Fill Cap before starting the engine.
See your Engine Owner’s Manual for more detailed information.

16 DR® SNOW BLOWER
Operating the DR Snow Blower
1. Start the engine as described on the previous page.
2. After the engine has warmed up, set the Throttle to maximum speed.
3. Move the Shift Lever to the desired gear (see “Selecting Gears” in the next
section.
4. Make sure the Snow Blower Auger is clear of snow before engaging the
Auger Control Lever (Figure 32).
5. To start the Snow Blower Auger, push the Auger Control Lever down to the
Handle.
6. Gently squeeze the Drive Control Lever to engage the Wheels.
7. Upon completion of your work, allow the Auger to operate for a minute or
two to remove buildup and prevent icing.
8. Release the Drive and Auger Levers and pull out the Key to turn off the
engine.
Selecting Gears
The Snow Blower has six forward gears (Figure 33) that are labeled 1
(slowest) to 6 (fastest).
There are two reverse gears that are labeled R1 (slowest) to R2 (fastest).
Changing the Discharge Chute Rotation
The Discharge Chute Rotation can be set to any position within a 190 degrees
radius for ease of snow removal.
1. Rotate the Chute Rotation Knob until the desired angle is achieved (Figure
34). Rotate clockwise to rotate the Chute to the right. Rotate
counterclockwise to rotate the Chute to the left.

If the Auger strikes a foreign object or if your machine should start making an unusual noise or vibration, immediately release
the Levers, stop the engine and wait for all moving parts to come to a complete stop. Inspect for any damage and repair or
replace any damaged parts before restarting and operating the machine.
Never use DR Blower as a snowplow. Do not push the snow; let the snow thrower work its way through the snow.
If the ground speed of the machine is too fast, release the Drive Control Lever and shift to a slower speed to prevent the
discharge chute from becoming overloaded and clogged.
In deeper snow you can raise the Snow Thrower by pushing down on the handlebars to remove some of the top layer of snow
first, or take a half-width pass. A second or third pass will remove the remaining snow much easier.
Always ensure the Drive Control Lever is released before shifting gears to
prevent damage to the machine and possible injury to the operator.

Changing the Chute Height
The angle of the top portion of the Chute can be adjusted up or down to change
the distance that the snow is being thrown.
1. Move the Chute Height Control forward to lower the Chute Deflector for
Blowing the snow shorter distances (Figure 35).
2. Move the Chute Height Control back to raise the Chute Deflector for longer
distances.
Operating the Grip Warmers
1. Move the Switch to the forward (ON) position to turn on the heat to the
Grips (Figure 36).
2. Move the Switch to the rear (OFF) position to stop heat to the Grips.
Operating the LED Headlight.
1. Move the Switch to the forward (ON) position to turn the Headlight on
(Figure 36).
2. Move the Switch to the rear (OFF) position to turn the Headlight off.
Using the Drift Cutters
Drift Cutters will cut through snow that is taller than the top surface of the
Auger Housing. This will keep the snow at the sides separated better and
provide a more consistent cut path in deeper snow.
Adjusting the Skid Shoes
The Skid Shoes can be adjusted to work best with the surface you are working
with. For smooth pavement without defects, the Skid Shoes can be set to the
lowest position. If the surface is a gravel consistency, you should raise the Skid
Shoes to a height that allows the most snow to be removed without disturbing
the gravel surface.
1. Loosen the two Jam Nuts using a 1/2" Wrench (Figure 37).
2. Position the Skid Shoes to the desired height and tighten Jam Nuts.
Note: Both Skid Shoes should be set at the same height.
Clearing out a Clog in the Auger and Discharge Chute
1. Use the Shovel that is secured to the top of the Auger Housing when
clearing snow from the Discharge Chute or Auger Housing (Figure 38).
2. Start the machine to clean out remaining material and repeat cleaning
process as needed until snow discharges freely.
