SYSTEM OVERVIEW:
The steering system incorporated on the TANK-S Unit is a system that coordinates the steer angle of the front wheels and the speed of the rear wheels when negotiating a turn. The front steering assembly is connected to the drive wheel hydraulic pumps by a coordinated linkage system. As the front wheels are turned in a direction, the speeds of the rear wheels are synchronized to match the exact speed required for the turn created by the steer angle of the front wheels.
The hydraulic steering system consists of a pump, a valve located in the steering column and a cylinder connected to the front linkage. Turning the steering wheel, rotates the control valve sending a calibrated amount and pressure of fluid to the steering cylinder. The cylinder positions the front wheels for the desired turn radius.
The drive system consists of separate RH and LH pumps and RH and LH drive motors. Mechanical linkage from the front steering system and a manually operated foot pedal connected to the individual pumps control the speed and rotational direction of the motors.
The system is supplied from a common reservoir and filter.

MAINTENANCE SCHEDULE:
Daily: (Highly Recommended)
Check the Hydraulic Oil Level in the reservoir.
Low fluid level will enable the pumps to ingest air into the system or cause the system to run at temperatures above recommended levels. Both conditions will damage pumps and motors. High fluid level can cause the oil to leak by the filler cap or breather when the fluid expands during operation. Normally, this does not result in component damage.
Check the Hydraulic Hoses and Fittings for leaks, abrasion, kinks, twists or flattened hoses.
A leak in the system can cause the fluid level to drop below the recommended level during the course of a day.
Leaks must be addressed immediately to avoid damage to components.
Kinks, twists or flatten hoses can restrict fluid flow. Restricted fluid flow can cause cavitation within the pumps causing permanent damage.
Clean debris from the cooling fan, radiator screen and fins, and pump housings. Each pump has a cooling fan mounted directly on the pump shaft.
Debris covering the fan guard/screen restricts air flow essential for proper cooling.
The radiator located at the rear bumper cools the return fluid before it returns to the reservoir. Operating the unit without proper cooling can cause premature hydraulic fluid breakdown and damaged seals, gaskets etc.
First 50 Hours: (Mandatory)
Change the Hydraulic Oil and Filter. (See Specifications)
Most initial wear or break-in of internal metal components takes place during the first 50 hrs. Particles are suspended in the reservoir fluid and are captured in the filter before recalculating through the system.
The amount of particles captured in the filter can restrict fluid flow to the pumps causing cavitation resulting in poor performance or component damage.
Every 100 Hours: (Highly Recommended)
Change the hydraulic oil filter if unit is operated under severe conditions.
On the S-Series TANK , changing the filter is relatively easy and inexpensive.
Changing the filter frequently especially under severe operating conditions will insure that the fluid going through system is clean and unrestricted.
Check the condition of the Hydraulic Oil / Fluid for Contamination and Break Down. Light or milky color indicates water or air contamination.
Dark color or opaque indicates breakdown from heat or excessive component wear.
*Change the hydraulic oil and filter if any of the above conditions are evident.
* If the hydraulic oil appears contaminated or dark colored, monitor and service more frequently than the recommended schedule.
Every 500 Hours: (Mandatory)
Change the Hydraulic Oil and Filter. (See Specifications).
Under normal operating conditions, at about 500 hrs., the Hydraulic Oil may begin to breakdown.
The lubricity and the effectiveness of the oil additives may begin to loose their properties due to normal wear and heat.
Contaminants as wear particles, dirt and moisture are usually evident after the duration of the recommended time period.
*It is imperative that the Fluid and Filter be changed at this time.
*Units used under extreme or severe operating conditions the system should be serviced more frequently than the recommended schedule.
NOTE: Failure to follow the recommended maintenance schedule can effect performance and shorten the service life of components within the system.
Failure to follow the mandatory service items can jeopardize warranty coverage.
