Read the complete mounting instructions that follow before you begin. Damage to the equipment or personal injury could result. Make sure all operating and residual pressures are relieved before working on a hydraulic system. Keep unprotected body parts, such as face, eyes, and arms as far away as possible from a suspected leak. By modifying an existing chain, it can be used to dig the width you want and thus save going the expense of a whole new digging chain assembly. The higher the auger, the closer to the trench the spoil will be placed.
Use only manufacturer recommended replacement parts. This will raise the auger and thus leave the dirt or spoil closer to the trench. A diagram and parts list of all mounting and hydraulic kits can be found in Section E and the trencher assembly can be found in Section I. Never let anyone work around, or perform maintenance on the trencher while it is running. Position the skid steer so that the top of the toolbar is in under the lip on the adaptor plate. Read all safety warnings before operating the trencher. Do not use the trencher or crumber bar as a step, or grab the digging chain when climbing on or off the trencher.
For information on chain, sprocket, boom, and crumber options see Sections I and J. Make sure all safety devices are in place and working. These units can be identified by the absence of a grease zerk in the bearing. Be sure to read all decals before operating the trencher. If shaft is turning but sprocket is not, stop the trencher and tighten the sprocket clamp.
You cannot trench driving the skid steer forward. We therefor strongly recommend that you take the extra time to follow these procedures whenever your trencher will not be used for an extended period of time. Read your skid steer owner's manual for information regarding skid steer operation before attempting to use the trencher. It is the skill, care, common sense, and good judgment of the operator that will determine how efficiently and safely the job is performed. Repeated stalling of the trencher will cause oil to overheat rapidly and should be avoided. The couplers must also mate up to the skid steer's auxiliary hydraulic system couplers.
This will reduce the shock to the skid steer and trencher when the digging teeth first contact the ground. See maintenance Section L in this manual. Replace operating decals if damaged or in unreadable condition. Do not operate the trencher with protective equipment removed. Set the skid steer throttle at half speed.
Below is a diagram of the chain's basic components with their descriptions and corresponding part numbers. Rotate the pin until its flat side lines up with the corresponding flat side of the connector link hole and tap the pin on through. Never attempt to free a stuck chain with the unit running. In the event yours was not installed -attach the side shift mounting frame to the trencher by sliding the two side shift inner tubes part 78824 through the trencher mount lining up one set of side shift holes and installing the lock pin part 79113. Sand can build up in the sprockets effectively increasing the chain tension.
Never try to make sharp turns while trenching. The digging tooth make up of each digging station is given in code. It is important however, to be familiar with, and know the controls and adjustments on both the trencher and the skid steer. With it you will be able to better understand the rest of this section. When teeth wear out, production will drop sharply, increasing wear and tear on other components. Never work on, or make adjustments to any part of the trencher while the unit is running. You may need to order more than just a chain assembly.
Order any parts required and make necessary repairs to avoid delays when starting next season. Relief valves should be checked and adjusted only by a trained service technician. They are included for your safety and for the safety of others working with you. The trencher uses the skid steer's quick-change attaching system for ease on installation. Inspect couplers and hoses for dirt, rust, and other contaminates and repair or replace as needed. Will you have to work around others? Operate chain for a short period to work the oil into the pins. Set the quick-change attaching lock on the skid steer toolbar to the unlocked position.
