ROHRER MANUFACTURING 99E-Y (01) PDF MANUAL

Do not “dry fire” or activate tool without t-post in position.

Always wear eye/ear protection.

Wear protective foot gear.

Keep hand clear of Clamp Sleeve (2) when driving post.

Do not exceed design pressure of 70-75 PSI for 98E, 70-80 PSI for 99E-X, 80-90 PSI for 99E-Y, 90-100 PSI for 99E-M, and 90-110 PSI for 99E-W.

Disconnect air from driver when not in use.

The T-Post Driver has been calibrated to operate between 75-85 strokes per minute at design pressure (70-75 PSI for 98E, 70-80 PSI for 99E-X, 80-90 PSI for 99E-Y, 90-100 PSI for 99E-M, and 90-110 PSI for 99E-W) with a minimum of 2.5 cubic feet of compressed air.

For optimum performance and operation safety, DO NOT operate at higher pressure. Operation of T-Post Driver at pressures above design pressure will negate the warranty.

DO NOT attempt to operate Driver on solid surfaces such as rock or concrete.

If Driver quits operating due to rock or other solid materials, STOP operation, then move Driver with post to left or right and try again.

DO NOT “dry fire” or activate tool without t-post in position.

Set air pressure at design pressure.

Read this manual completely before operating.

To ensure peak performance lubricate tool regularly. Use 20 weight hydraulic oil or 5/30 motor oil. Start by placing 5-6 tablespoons of oil in the end of the air hose at the air compressor end. If not using an Inline Oiler (mounted to air compressor) for every 1 1/2 – 2 hours of steady use, add 2-3 teaspoons of oil to your hose, always at the compressor end.

Keep tool clean and free of dust. See “Maintenance” information for further details.

Attach male air hose fitting-connector to center hole on body (4).

Slide t-post into the Sleeve (2).

Stand unit up into a vertical position sliding the t-post up to the top of the driver.

Snugly tighten Clamp Handle (5). Do not over tighten.

Before connecting the air hose, Control Lever (3) must be in up/off position.

DO NOT start tool without being loaded with a t-post, and in a vertical-upright position.

Connect air hose.

To ensure the t-post has a proper start, place left foot on spade on t-post and/or grasp Grip Handle (7) and exert downward pressure.

Maintain firm hold on Grip Handle (7) and a relaxed grip on driver Handle (1) for easy operation.

Move Control Lever (3) to down/on position to activate driver.

Handle (1) and driver body will move up 7 inches, followed by a downward stroke.

When t-post reaches desired depth, hold Control Lever (3) in up/off position during downward stroke and driver will STOP.

Loosen Clamp Handle (5) and remove driver from newly driven t-post.

While air hose is connected to driver, extreme caution is necessary when handling tool.

A dry fire of tool may cause injury and damage tool.

If lubricant on o-rings is stiff due to cold weather conditions: Apply liberal amounts of 20# hydraulic oil at the center valve opening (4). Place the control lever (3) in “down/on” position, apply several drops of oil, then place control lever in “up/off” position and apply oil again. Work out stiff lubricant.

If air exhaust on valve is clogged: Clean speed control orifice (6).

If o-rings are dirty and/or dry: Clean and lubricate. An inline oiler can be used to keep tool and o-rings lubricated.

If after prolonged storage o-rings have dried out and cracked: clean piston shaft and replace o-rings.

If air compressor is not charged or not working correctly: Check pressure gauge on compressor.

Tighten Clamp Handle (5).

If T-Post driver has hit solid material such as rock or concrete: Stop operation and move left or right and try again.

If o-rings are dirty and/or dry: Clean and lubricate.

If air compressor is not charged or not working correctly: Check pressure gauge on compressor.

Keep dry clean and free of dirt and dust.

Cover air inlet when not in use.

Cover tool to protect from dirt and dust when not in use.

An inline oiler is highly recommended for proper lubrication and maintenance.

Drain air compressor of excessive moisture prior to use.

Many times air tools that are believed to be defective or performing poorly are often found to be dirty and dry of lubricant. Usually cleaning and oiling with the proper lubricant is all that is necessary to bring the tool back to near original performance.
