Slope Safety
-
Operate the machine up and down slopes with the heavy end of the machine uphill. Weight distribution changes with attachments. An empty attachment makes the rear of the machine the heavy end, and a full attachment makes the front of the machine the heavy end. Most other attachments make the front of machine the heavy end.
-
Keep the attachment in the lowered position when on slopes. Raising the attachment on a slope affects the stability of the machine.
-
Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operating the machine on any slope or uneven terrain requires extra caution.
-
Establish your own procedures and rules for operating on slopes. These procedures must include surveying the site to determine which slopes are safe for machine operation. Always use common sense and good judgment when performing this survey.
-
Slow down and use extra care on hillsides. Ground conditions can affect the stability of the machine.
-
Avoid starting or stopping on a slope. If the machine loses traction, proceed slowly, straight down the slope.
-
Avoid turning on slopes. If you must turn, turn slowly and keep the heavy end of the machine uphill.
-
Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction.
-
If you feel uneasy operating the machine on a slope, do not do it.
-
Watch for holes, ruts, or bumps, as uneven terrain could overturn the machine. Tall grass can hide obstacles.
-
Use caution when operating on wet surfaces. Reduced traction could cause sliding.
-
Do not operate the machine near drop-offs, ditches, embankments, or bodies of water. The machine could suddenly roll over if a wheel or track goes over the edge or the edge caves in. Maintain a safe distance between the machine and any hazard.
-
Do not remove or add attachments on a slope.
-
Do not park the machine on a hillside or slope.
-
Do not pull a trailer on any slope.

Operation
Installing and Removing the Attachment
Refer to the Operator’s Manual for the traction unit for the installation and removal procedure.
Important: Before installing the attachment, position the machine on a level surface, ensure that the mount plates are free of any dirt or debris, and ensure that the pins rotate freely. If the pins do not rotate freely, grease them.
Note: Always use the traction unit to lift and move the attachment.
Warning
If you do not fully seat the quick-attach pins through the attachment mount plate, the attachment could fall off the machine, crushing you or bystanders.
Ensure that the quick-attach pins are fully seated in the attachment mount plate.
Warning
Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury; otherwise, gangrene may result.
-
Ensure that all hydraulic-fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system.
-
Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.
-
Use cardboard or paper to find hydraulic leaks; never use your hands.

Using the Boring Unit
Digging a Trench
Before drilling under a walk or driveway, you must make an entrance and an exit trench on either side of the drilling area (Figure 4).
-
Both trenches must be at least 15 cm (6 inch) wide and 46 cm (18 inches) deep.
-
The entrance trench must be at least 2.13 m (7 ft) long and perpendicular to the walk or driveway.
-
The exit trench must be at least 0.91 m (3 ft) to 1.8 m (6 ft) long, parallel to the walk or driveway, and centered across from the entrance trench.
Boring a Hole
Important: Boring is a 2-person operation. Do not attempt to perform this operation by yourself.
-
Position the traction unit with the drive head at the beginning of the trench and lower it to the appropriate depth.
-
Shut off the engine, remove the key, and wait for all moving parts to stop.
-
Connect a rod and boring bit onto the drive head.
-
Connect the rod guide tool to the rod just behind the boring bit (Figure 5).
-
With the person guiding the boring bit positioned to the right of the trench (Figure 5), start the engine, move the pump selector valve to the SLOW position (200 and 300 series traction units only), move the throttle to midway between the SLOW and FAST positions, and pull the auxiliary hydraulics lever rearward to start the forward rotation of the boring bit.
-
Slowly move the traction unit forward, while the person with the rod-guide tool guides the boring bit into the soil (Figure 5).
