Introduction
1. The snowblower is capable of amputating hands and feet and throwing objects. Failure to observe the
following safety instructions could result in serious injury or death.
2.
Serious accidents which may cause injury or property damage can occur
guidelines are not followed. The operator is solely responsible for accidents or hazards that occur
when using the snowblower. Preventing accidents is the responsibility of every equipment operator.
Accidents can be prevented. Be careful before, during and immediately after use of any powered
equipment. The following general safety precautions must be fully understood and followed during
operation. Review these instructions frequently and never take chances. If you do not understand any
part of this manual or need assistance, contact your authorized, servicing Honda lawn tractor dealer.
Training
1. Read, understand and follow all instructions in this manual and on the snowblower before starting. To
order a replacement manual, contact an authorized, servicing Honda lawn tractor dealer, or Honda

the machine and attachment.
If
these labels are damaged or not legible, clean or replace them.
Preparation
1. Wear proper clothing when operating the snowblower. Always wear sturdy footwear (preferably

Before Operation
1.
Before each use, clear work area of objects such as rocks, toys, wire, sleds, etc., which could be
picked up and thrown.
2.
Keep the snowblower in safe operating condition. Check the following each time before use:
a) All hardware for tightness (refer to the torque table for details).
b) Inspect auger and fan blades for wear or damage. Broken pieces thrown from worn or damaged
auger or fan can cause serious injury.
c) Check for and maintain correct lawn tractor tire pressure. Check tires for cuts or bubbles. Check
wheels for damage or for missing hardware. Repair or replace as required.
d) Check the engine oil level and add oil as required. If oil level falls below the maximum fill mark, do
not run engine.
3.
Do not operate the snowblower without safety devices and shields in place and operating properly.
4. Use counterweights (purchased separately) for extra traction and proper balance.
5.
Check the lawn tractor brake function frequently. Adjust and service as required.

Snowblower Safety Recommendations
11. As a general rule, do not operate the machine in reverse. If it is absolutely necessary to back up:
a) Disengage the PTO clutch.
b) Check the area on the ground directly behind the machine.
c) Continue to observe area down and to the rear while backing up.
12. Approach blind corners cautiously.
13. Always observe the terrain. Watch for and avoid obstacles, stay away from holes, ditches, soft or
steep embankments and other potentially dangerous terrain.
14. Wet surfaces reduce traction and stability. Always maintain proper traction. Grip the lawn tractor
steering wheel firmly.
15.
Slow down before turning.
16. Watch out for traffic when operating near or crossing roadways.
17. Never leave a running machine unattended. Always disengage the PTO lever, set the parking brake
ON, and remove the ignition key before dismounting.
Children
1. Accidents can occur if the operator is not alert to the presence of children. Children are often attracted
to the machine and the snowblowing activity. Never assume that children will remain where you last
saw them.
2.
Never allow children to operate the machine, even under adult supervision. Local regulations may restrict
operator age. Allow only responsible adults, who are familiar with these instructions, to operate this unit.
3. Never carry children as passengers. They may fall off or be seriously injured or interfere with safe
machine operation.
4. Keep children out of the work area and under the watchful eye of another responsible adult.
5. Be alert and turn off the machine if children enter the area.
6.
Before and when backing up, look behind and down the operating area for small children.
7.
Use
extreme care when approaching blind corners, drifts, trees or other objects that may obscure
vision.
8.
Keep children away while performing maintenance or adjustments.

Snow Removal Methods
OKAY
Use the following patterns to avoid discharging snow in
unwanted locations and to prevent a second pass. For
clarity, assume both methods are used on a rectangular
area.
If
you can discharge snow to both sides, it is best to
start in the middle of the rectangle. Operate the
snowblower from one end to the other, discharging
snow to both sides. This method permits you to leave
the discharge chute in the same position.
If you must discharge snow to only one side, start in
one corner, then rotate the discharge chute with each
pass. This method will require a bit more effort, but the
snow will be discharge only to one side.

To decrease lifting effort, increase the length of the
exposed threads by tightening the hex nut on each
bolt. To increase effort, loosen the hex nut on each
bolt. When making any adjustments, always make sure
