Climbing equipment may be required to access this service point. Refer to the Operation and Maintenance Manual, "Mounting and Dismounting" topic for safety information.

Show/hide table

Before servicing/performing maintenance on the machine, electrical power must be physically disconnected; battery plugs must be disconnected from the batteries, or the trailing cable must be unplugged, and warning tags and padlocks shall be applied by a certified electrician. Certified electricians shall perform or direct any electrical work, including any energized testing, repair work in controllers, motors, or other approved compartments, and shall insure that all compartments are properly closed and inspected prior to re-energization. All applicable lock out and tag out procedures must be followed.

Show/hide table

Do not operate the machine if any guards or covers are missing or inadequately secured. Personnel could be seriously injured or machine damage may occur.

Show/hide table

Observe the safe working load limits of all lifting and blocking devices and keep a safe distance from suspended/blocked loads. Personnel may be seriously injured or killed by falling loads.

Cleaning Procedure

Note: Use a mild diluted soap and water mixture for the cleaning of all polycarbonates.

Special Note:

The edges of your polycarbonate window are not protected with a chemical resistant hard coating. Do not allow chemicals, cleaning solutions, or solvents to come in contact with the edges of the window. Always rinse window and window edges thoroughly with generous amounts of lukewarm clean water.

General Cleaning

1. Wash thoroughly with warm water to remove the surface material, grit, and grime.

2. Using a soft microfiber cloth or moist non-abrasive sponge, gently wash with a mild diluted soap or detergent.

3. Rinse with the lukewarm clean water. To prevent the water spots, thoroughly dry the glazing with a dry soft cloth.

Removing Heavy Oils and Tars

1. Wash thoroughly with warm water to remove the surface material, grit, and grime.

2. Using a soft non-abrasive cloth, gently wash with an equal quantity mixture of isopropyl alcohol and water.

3. Rinse with the lukewarm clean water. To prevent the water spots, thoroughly dry the glazing with a dry soft cloth.

Compatible Cleaners

The following cleaning agents are compatible with the polycarbonate when used according to the manufacturer recommendations:

Liquid Detergents (Diluted in Water):

• Joy^® Liquid

• Palmolive^® Liquid

Glass Cleaners:

• Windex^® Crystal Rain (ammonia free)

• Sparkle^®

Note:

1. Do not use abrasive cleaners.

2. Do not use high alkaline cleaners (high pH or ammoniated).

3. Do not leave cleaners sitting on polycarbonate for longer duration. Wash off immediately.

4. Do not apply cleaners under the direct sunlight or at elevated temperatures.

5. Do not clean your polycarbonate with any unapproved cleaners. When in doubt, seek guidance.

6. Using scrapers, squeegees, razors or other sharp instruments may permanently scratch your polycarbonate.

7. Always avoid dry rubbing or cleaning your polycarbonate, as sand and dust particles clinging to the exterior of the glazing may scratch the surface.

8. An anti-static canned-air ionizer can reduce the electrostatic charge buildup on polycarbonate, consequently reducing dirt and dust buildup that would hinder cleaning.
