Inspect and Clean Polycarbonate Windows
Polycarbonate windows are important for the protection
of the operator and the safe operation of the machine.
Inspect the windows system regularly, and if surface
crazing or cracks are observed, replace windows using
only Hitachi replacement parts to ensure the original
operator protection level. Inspect the windows after any
signicant impact to the windows or frame.
NOTE: The use of cleaning agents, solvents,
polishing compounds, or waxes not listed in this
instruction block is not recommended. Contact
an authorized dealer for additional information
regarding glazing materials.
IMPORTANT: DO NOT use glass cleaners on
polycarbonate windows.
NEVER use abrasive or highly alkaline cleaners
on polycarbonate windows. Some cleaning
compounds may attack the polycarbonate
material, resulting in cracks.
NEVER use aromatic or halogenated
solvents like toluene, benzene, acetone,
tetrachloride, or petroleum products. Gasoline
should not be used.
Acceptable cleaning agents are John Deere
Polycarbonate Cleaner and John Deere
Polycarbonate Wash.
Acceptable soap based cleaning agents
are Joy®, Palmolive® Liquid, and Scott®
Pink Lotion Skin Cleanser.
Cleaning should never be done in direct sunlight or at high
temperatures, as this can lead to staining.
Before washing or applying any cleaning agents
or solvents, inspect the hard coating of window for
microcrazing or cracking. Do NOT apply solvents or
cleaning agents to window with microcrazing or cracks.
Minor scratches and abrasions can be minimized by using
a bufng compound or polish agent like NOVUS 1 or 2.
Test any intended polishing product in a small area before
using on the entire window. All polishing should follow
the manufacturer’s instructions to prevent further damage
to the window’s hard coat.
To begin the cleaning process, ush away as much loose
dirt as possible with water, then clean the windows using
a solution of approved cleaner and lukewarm water. Use
a soft, grit-free cloth or sponge to loosen any dirt or grime.
Never scrub with brushes, steel wool, or other abrasive
materials. Never use squeegees, razor blades, or other
sharp instruments to remove deposits or spots. The
windows are made of a polycarbonate material, which
is less abrasion resistant than glass. The windows will
scratch.
Use of incompatible cleaning materials can cause
structural and/or surface damage.
IMPORTANT: Always rinse window with water
prior to cleaning process.
The edges of polycarbonate sheet are not
protected with an abrasion and chemical
resistance coating. Do not allow cleaning
solutions and solvents to pool along the edges
at any time. Always rinse edges thoroughly with
generous amounts of clean, lukewarm water.
CAUTION: Make sure the work area is well
ventilated when working with organic solvents.
Solvent fumes can be hazardous to health if
proper safety precautions are not taken.
Do not smoke around organic solvents.
Solvents can cause risk of re if proper safety
precautions are not taken.
For all mentioned chemicals, consult the
manufacturer’s material safety data sheet (MSDS)
for proper safety precautions.
Masking adhesive and glazing compounds can be
removed by applying Isopropyl Alcohol or Naphtha VM&P
grade to a soft cloth and rubbing lightly; additionally, any
of these cleaning agents or butyl cellosolve can be used to
remove paints, marking pen inks, lipstick, or other forms
of grafti. Afterwards, wash the window using a solution of
approved cleaner and lukewarm water. Rinse thoroughly
to remove any trace of solvents.
Masking tape and adhesive tape work well for lifting off
old, weathered paints.
To remove labels and stickers, the use of kerosene is
generally effective. If the solvent does not penetrate the
sticker material, apply heat using a hair dryer to soften
the adhesive and promote removal. Afterwards, wash the
window using a solution of approved cleaner and lukewarm
water. Rinse thoroughly to remove any trace of solvents.
To remove tree sap, ush away as much loose dirt as
possible, then use John Deere Polycarbonate Cleaner,
kerosene, or Naphtha VM&P grade on a soft cloth and rub
lightly. Rinse well with clean water and dry with a chamois
or softer cloth to prevent water spotting.
