EMISSION CONTROL SYSTEM INFORMATION
The U.S. and California Clean Air Acts
EPA and California regulations require all manufacturers to furnish written instructions describing the operation and maintenance of emission control systems. The following instructions
and procedures must be followed in order to keep the emissions
from your DEK engine within the emission standards.
SAFETY LABEL LOCATIONS
These labels warn you of potential hazards that can cause serious injury. Read them carefully. If a label comes off or becomes
hard to read, contact your DEK lawn mower dealer for a replacement.
SAFETY INFORMATION
DEK lawn mowers are designed to give safe and dependable
service if operated according to instructions. Read and understand this owner’s manual before operating your lawn mower.
OPERATOR RESPONSIBILITY
Know how to stop the lawn mower quickly in case of emergency. Understand the use of all lawn mower controls, output
receptacles, and connections. Be sure that anyone who operates the lawn mower receives proper instruction. Do not let
children operate the lawn mower without parental supervision.
Mower Inspection
For your safety, inspect the lawn mower before each use of operation. In order to inspect your lawn mower, the following conditions should be met: the lawn mower should be on a flat and level
surface, with the ignition switch off, key removed, and blades disengaged. Also the spark plug wire should be off of the spark plug.
1. Walk around the mower and look for any fluid spills or leaks
on or underneath the mower. Remove any and all excessive debris, dirt, and/or fluids.
2. Look for signs of damage or excessive wear. Check the
tightness of all nuts, bolts, pins, and screws. Tighten any
that may be loose and replace any that are missing.
3. Be sure the safety interlock controls are operating properly
so that the engine cannot be started unless the ground
speed control lever is in neutral and the blades are disengaged.
4. Check the mower blades for any damage or abnormal wear
and replace in sets so that they are balanced.
5. Check the tire pressure on all four tires. See page 15 for
instructions

Operation of Equipment - Safety Cautions
WARNING
DANGER: GASOLINE IS HIGHLY FLAMMABLE AND EXPLOSIVE. Do not add fuel while the engine is running or is hot.
Keep open flames, sparks, and heat away from the fuel and
store fuel in containers specifically designed for that purpose.
ADD FUEL OUTDOORS ONLY AND IF THE FUEL IS SPILLED,
DO NOT START THE ENGINE. Manually push the mower away
from the spill and wipe up immediately.
WARNING
Do not use your DEK lawn mower to carry passengers. When
people, especially children, an pets are close by, avoid mowing
since rotating blades can throw rocks and other items, which can
cause serious injury.
Before Using Your DEK Lawn Mower
CAUTION
When operating your DEK lawn mower, wear protective clothing
while mowing. Long pants and safety glasses will help reduce
the risk of injury from thrown objects. It is recommended that
adequate footwear, such as steel toe shoes with aggressive
soles, be worn to help protect your feet and maintain traction on
slopes or uneven grounds. Always wear hearing protection.
Inspecting Your Lawn Mowing Area
Inspect the area where your DEK lawn mower will be used. Check for
stones, sticks, wire, and other foreign objects. These objects may
become projectiles that can cause serious injury and/or deat h when
struck by the mower.
1) Do not operate the engine in a confined space where dangerous carbon
monoxide fumes can collect. Carbon monoxide is odorless, tasteless,
and can be fatal.
2) Mow only in daylight.
3) Make sure the mower is in neutral and the blades are disengaged before attempting to start the engine.
4) Do not stop or start suddenly when going uphill. Never use riding attachments on slopes since there is an increase risk that they might roll
over.
5) Avoid steeps slopes and use extreme caution when changing directions
while operating on a slope.
6) Be extremely careful when operating on a slope or when the grass is
damp or wet. Reduced traction could cause sliding. Never mow by
pulling the mower back towards you because you might slip.
7) Watch for traffic when crossing surfaces other than grass (i.e. transporting) loading a trailer or vehicle, or when the mower is not in use.
8) Never operate the mower with defective guards, shields, or without the
safety devices securely mounted in place.
9) Never direct discharge of material toward bystanders nor allow anyone
near the mower during operation.
10) Do not change the governor settings or over speed the engine.
11) Always stop the engine whenever you leave the mower, even for a
moment.
12) To help reduce the risk of a fire hazard, keep the engine and the area
around the engine free of grass, leaves or any other type of foreign
material.
13) Beware of cutting edges. Always wear gloves for safety when performing blade maintenance activities. Beware on multiple blade units since
the rotation of one blade may cause the rotation of the other blade.
14) Do not store or operate the mower with the grass chute deflector in the
raised position. Serious injury could occur.
