Operating Instructions 

Starting the Engine 

WARNING 

DANGER: DO NOT OPERATE THE ENGINE IN A CONFINED 
SPACE WHERE DANGEROUS CARBON MONOXIDE FUMES 
CAN COLLECT.  CARBON DIOXIDE IS ODORLESS, TASTE-
LESS AND CAN BE FATAL. 

NOTE: Check to make sure you have added fresh unleaded gasoline

 

and filled the engine with SAE 5W30 motor oil

 

before starting your 

mower.   

1. 

Check to make sure the 
shut off valve, located at 
the bottom of the tank is in 
the “ON” position.  

        (Figure 1) 

Note:  there is also an fuel         
valve on the carburetor of the 
Honda powered 36” mowers. 
 
 

 
2. 

Check to make sure the 
brake is set. (Figure 2) 

 
 
 
 
 

3. 

Check to make sure the 
gear shift lever is in the 
neutral position.  The lever 
should be on “N” - 

belt 

drive model only.

  There 

is a safety switch that pre-
vents the mower from 
starting when in gear.  If 
the lever is not firmly on 
the “N” the engine will not 
start.       (Figure 3)

Figure 3 

4. 

Make sure that the blade control lever is in the “OFF” position.   

NOTE:  The safety interlock system  will prevent the engine 
from being started if the blade control lever is not in the 
“OFF” position and the gear shift lever is not in the neutral 
“N” position.

 

5. 

Slide the engine speed control to the top

 

position or to “CHOKE” 

if the engine is cold (some models have a separate choke lever 
to pull out). 

6. 

Turn the key clockwise to the “Start” position for electric start 
models or “On” for pull start models. 

7. 

Slowly pull the start cord on the engine until just past compres-
sion.  STOP!  Return the start cord and then pull firmly with a 
smooth, steady motion to start the engine. 

8. 

When the engine starts to run, slowly return the engine speed 
control out of “CHOKE” to the desired engine speed (or push 
choke lever “off” on some models). 

Going Forward (belt drive models): 

CAUTION 

Before attempting to use your DEK mower, please make sure you 
are familiar with all of the components and have read the manual.

4. 

Release the brake control lever locks by squeezing both     
traction control levers as much as needed while at the same 
time, applying forward pressure on the brake control lever 
locks with your thumbs. 

5. 

Slowly and evenly, let both traction control (brake / clutch) 
levers down simultaneously and the mower will start to go in 
reverse.

either the blade control lever is in the “ON” and/or the gear 
shift control lever is out of the neutral position, and safety 
interlock system will stop the engine.  To restart the mower, 
reset all controls to the “OFF” position and neutral “N” posi-
tion.
