Cleaning Guide

IMPORTANT:

Regular and thorough cleaning

of machine combined with other routine

maintenance procedures listed in the

Operator’s Manual greatly reduce the risk

of fire, chance of costly downtime, and

improve machine performance.
Crop material and other debris can

accumulate in various areas. Direction of

wind, type of crop, and crop moisture

content can all impact where and how much

crop material and debris can accumulate.

Be aware of harvest conditions and adjust

your cleaning schedule to ensure proper

machine function and to reduce the risk of

fire.

These areas may require more frequent

cleaning, even multiple times per day,

depending on harvest conditions.

Inspect and

clean these areas as needed throughout the

harvest day.

Other areas not covered in this section may

also collect crop debris and MUST be cleaned

periodically for machine function and

appearance.

Thoroughly inspect the entire machine on a

regular basis throughout the harvest season.
Refer to the Machine Cleanout Section of

your Operator’s Manual for further

information.

READ SAFETY INFORMATION IN
OPERATOR’S MANUAL
Always follow all safety procedures posted

on the machine and in the Operator’s

Manual. Before carrying out any inspection

or cleaning, always shut OFF engine, set

parking brake and remove key.
Thoroughly clean machine from top to

bottom with compressed air. First clean all

areas accessible from engine deck. Start with

engine compartment and work outwards

and counterclockwise to other areas around

engine compartment, floor underneath

engine, top rear of rotor and rear deck,

including top of diesel particulate filter

(if equipped). Once top areas of machine are

clean, proceed to cleaning areas accessible

from ground level.

From ground level, clean rear underside

of fuel tank area and top of the rear

tailboard of the residue disposal system.

Diesel particulate filter area (if equipped)

will also need to be cleaned from ground

level. Once the cleaning from ground level

is finished, recheck engine compartment

for any crop debris that could have blown

in from ground level cleaning.
