FILLING THE SOLUTION TANK (REQUIRED FOR BOTH SWEEP MODE AND EXTRACT MODE) 1 Read the cleaning chemical label and calculate the proper amount of chemical to mix for a tank that holds 28 US gallons (110 liters). 2 Open the Solution Tank Cover (23). 3 Fill the tank 1/3 full of water, add the cleaning chemical then fi ll the tank to 7.62cm(3 inches) from the top of the tank opening. NOTE: The machine can either be used conventionally with detergent mixed in the tank or the detergent system can be used. When using the detergent dispensing system do not mix detergent in the tank, plain water should be used. CAUTION! Use low-sudsing, liquid detergents designed for carpet extraction. Water temperature should not exceed 130 degrees Fahrenheit (54.4 degrees Celsius).

BEFORE USING THE ES4000

Thorough vacuuming of the carpet to be cleaned is not necessary before using the ES4000 automatic extractor, due to the on-board sweeping broom and debris hopper. The area should be cleaned in Sweep Mode before being cleaned in Extract Mode.

PRE-SPRAYING THE CARPET

Pre-spray spots and heavy traffi c areas before extracting. Use a hand-held bottle sprayer or a pressurized “Hudson” type sprayer. Mix the pre-spray according to the chemical manufacturer’s directions.

Before you begin extracting, look at the area to be cleaned and plan your work. Divide the space into sections. Overlap each pass 2 inches (5 cm). DETERGENT SYSTEM PREPARATION AND USE (ONLY USED IN EXTRACT MODE) COMMON INSTRUCTIONS: Pressing and releasing the Detergent Switch (C) while in Restoration (H), Maintenance (G) or Prespray (I) mode will cause the detergent system to alternately turn on and off. When the detergent system is ON, the detergent pump will be activated at a specifi c rate while the solution pump is running. The detergent pump will turn OFF whenever the solution pump is not running or when the detergent system is turned OFF. Unless Prespray Mode (I) is selected, the detergent system will be OFF by default each time the machine is powered up with the Key Switch (A). The detergent system will be selected by default when Prespray Mode (I) is active. The Detergent ON / OFF Switch (C) is inactive when Sweep Power (D) is ON. The system should be purged of previous detergent when switching to a different detergent. SERVICE NOTE: Move machine over fl oor drain before purging because a small amount of detergent will be dispensed in the process. To Purge When Changing Chemicals:1 Disconnect and remove the detergent cartridge. 2 Turn the Key Switch (A) ON. Press and hold the Detergent ON / OFF Switch (C) and the Solution ON / OFF Switch (B) for more than 2 seconds while the controller is in any mode except standby to initiate a purge cycle. NOTE: Once activated the purge process takes 10 seconds. See illustration on next page for Detergent System indicators. Normally one purge cycle is adequate to purge the system.To Purge Weekly: 1 Disconnect and remove the detergent cartridge. Install and connect a Cartridge fi lled with clean water. 2 Turn the Key Switch (A) ON. Press and hold the Detergent ON / OFF Switch (C) and the Solution ON / OFF Switch (B) for more than 2 seconds while the controller is in any mode except standby to initiate a purge cycle. NOTE: Once activated the purge process takes 10 seconds. See illustration on next page for Detergent System indicators. Normally one purge cycle is adequate to purge the system. When the Detergent Cartridge (18) is almost empty a Display Panel (E5) indicator will come on. The “Low Detergent” indicator will remain on until you reset the system. Once this indicator comes on you should be able to simply pour an entire gallon bottle of detergent into the Cartridge to refi ll without worrying about measuring. NOTE: Only reset the system when the cartridge is full. When switching cartridges, the “Low Detergent” indicator is only accurate if the replacement cartridge is at the same level as the cartridge being replaced.To Reset: 1 Turn the Key Switch (A) ON. Press and hold the Maintenance Mode Switch (G) and the Restoration Mode Switch (H) for more than 2 seconds while the solution and detergent are ON. The Detergent Reset Icon will display for 5 seconds. See illustration on next page for Detergent System indicators.Detergent Ratio:1 The pre-programmed ratio can be adjusted.

WARNING! Be sure you understand the operator controls and their functions. While on ramps or inclines, avoid sudden stops when loaded. Avoid abrupt sharp turns. Use low speed down hills. Clean only while ascending (driving up) the ramp. CAUTION! Sweeping with a dry solution tank could reduce the life of the solution pump that powers the misting system.

FILLING THE SOLUTION TANK

While sweeping the ES4000 uses a misting system which sprays water into the airstream to dampen dust as it is drawn into the recovery tank. It is important that there be water in the solution tank at all times during sweeping so dust does not escape the system. Refi ll the solution tank before sweeping whenever the batteries have been recharged. Under normal conditions, a full solution tank should be adequate to supply the misting system through an entire battery cycle. To Sweep...

Charge the batteries each time the machine is used or when the Battery Indicator (E7) is reading less than full. WARNING! Charge batteries in a well-ventilated area. Do not smoke while servicing the batteries. When Servicing Batteries...* Remove all jewelry* Do not smoke* Wear safety glasses, rubber gloves and a rubber apron* Work in a well-ventilated area* Do not allow tools to touch more than one battery terminal at a time

• ALWAYS disconnect the negative (ground) cable fi rst when replacing batteries to prevent sparks.
• ALWAYS connect the negative cable last when installing batteries. CAUTION! Your voltage regulated lead acid (VRLA) battery will deliver superior performance and life ONLY IF IT IS RECHARGED PROPERLY! Under or overcharging will shorten battery life and limit performance. Be sure to FOLLOW PROPER CHARGING INSTRUCTIONS! DO NOT ATTEMPT TO OPEN THIS BATTERY! If a VRLA battery is opened, it loses its pressure and the plates become oxygen contaminated. THE WARRANTY WILL BE VOIDED IF THE BATTERY IS OPENED. If your machine shipped with an onboard battery charger do the following: Turn the Key Switch (A) OFF. Open the Battery Compartment (19) and the Battery Charger Access Door (8) for proper ventilation. Unwind the electrical cord from the side of the onboard charger and plug it into a properly grounded outlet. Refer to the OEM product manual for more detailed operating instructions. If your machine shipped without an onboard battery charger do the following: Open the Battery Compartment (19) and set the Prop-Rod (32). Disconnect the batteries from the machine and push the connector from the charger into the Battery Pack Connector (34). Follow the instructions on the battery charger. SERVICE NOTE: Make sure you plug the battery charger into the connector that attaches to the batteries. IMPORTANT: Make sure you have an appropriate charger for use on Gel cell batteries. Use only “voltage-regulated” or “voltage-limited” chargers. Standard constant current or taper current chargers MUST NOT be used. A temperature-sensing charger is recommended, as manual adjustments are never accurate and will damage any VRLA battery.A-18 / ENGLISH
