8 4. 5. Safe Operating Practices Basic safety rules should be followed by the operator of the Jarraff All-Terrain Tree Trimmer at all times. Careful supervision of the Jarraff is vital for safe operation. Both the operator and ground personnel should make an assessment of the terrain before operation. A visual and physical inspection of steeps, rocks, stumps, swamps, rivers, streams and the general condition of the terrain is essential to ensure safe negotiation in adverse conditions. The safety of personnel, tree trimming production, and the traveling capability of the Jarraff is the sole function of the operator s skill and proficiency. Operating the Jarraff improperly, beyond its stability limits, felling dangerously large tree limbs or improper cutting of tree limbs may cause serious injury to the operator, damage to public or private property, and serous injury to ground personnel also damaging the Jarraff unit itself. Safety is the responsibility of the operator; please follow all of the safety rules outlined in the Jarraff manual. Once the Jarraff All-Terrain Tree Trimmer is in operation, all ground personnel must remain a safe distance away from trimming operations, a minimum of 300 feet. Only one person should be operating the Jarraff at a time and no additional riders should be allowed before, during or after trimming operations. Always wait until the Jarraff is at a complete stop and turned off before exiting the machine. Never jump off a moving Jarraff All-Terrain Tree Trimmer. Not following the outlined safety procedures can result in personal injury or death. OPERATIONAL SAFETY PRECAUTIONS CAUTION! Before operating make sure operator is wearing the proper safety apparel: hard hat, safety glasses, safety shoes, safety gloves, safety vest, ear protection, the seat belt and anything else required by the specifications of the job. CAUTION! NEVER allow ground personnel to stand next to, come into contact with, or mount the Jarraff when the boom is near a power line. In spite of the dielectric characteristics of the non-conducting boom, hydraulic hoses, and insulated chain it is possible for moisture, dirt, debris, vines or etc. To conduct a ground short causing serious personal injury to the operator, ground personnel and others nearby or in contact with the Jarraff. CAUTION! The operator should always be aware of the over hang of the boom at the front of the Jarraff when the boom is in the cradle in the retracted and carry position. CAUTION! When moving in tight quarters, position ground personnel in a sight line with the operator to guide them in avoiding hazards or collisions. CAUTION! Check the height and width clearance of bridges, and also the load limits before traveling with the Jarraff. CAUTION! Watch for proper clearance when traveling. Be aware of overhead or side obstructions to avoid running into them. CAUTION! NEVER operate the Jarraff near a dangerous bank that could possibly cave in. CAUTION! NEVER swing the boom over ground personnel. CAUTION! NEVER get off the Jarraff while it is in motion. 8

9 CAUTION! NEVER allow riders on the Jarraff. CAUTION! NEVER operate with cab door open on the Jarraff. HYDRAULIC DEVICES Escaping fluids under pressure can penetrate the skin and cause serious personal injury. Observe the following precautions to avoid hydraulic hazards: 1. Tighten all connections before applying pressure. Relieve pressure when connecting or disconnecting hoses when servicing the unit. 2. Check for leaks with a piece of cardboard. Do not use hands! 3. Do not exceed working pressure of hydraulic hoses. 4. Visually inspect hoses regularly and replace if damaged.

49 Field Operation The stability of the Jarraff is inherently excellent because the boom is relatively light and the carrier vehicle is heavy enough and wide enough to negotiate most difficult terrains. The wheeled unit undercarriage has individual limitations, capabilities, grade abilities, stabilities, and ground pressure/flotation. A. WHEEL CONFIGURATIONS The Jarraff is delivered in Shipping wheel configuration, which is a narrow track width in order to prevent overhang on standard trailers IMPORTANT: Always use proper safety equipment. CAUTION: Prior to operation, the wheels MUST be adjusted to the wider track width. 1. On flat ground with machine off and parking brake set, jack up one end of the machine at a time so that the wheels on the axle being adjusted are off of the ground approximately 4 inches. 2. Remove ¾" hardware from the outer bolt circles only; leaving the axle plate fastened to the axle with the 7 8" nuts. (See Figures 1a & 1b) Figure 1a. Shipping Configuration Figure 1b. Shipping Configuration 3. Pull the wheel outward or away from the machine until the axle plate meets the rim plate. (See Figures 1c & 1d) 4. Reinstall ¾" hardware in this position and torque to 380 ft-lbs. 5. Reverse these steps to adjust back to shipping configuration. If you have any questions please, contact the Jarraff Service Department at

50 Figure 1c. Operating Configuration Figure 1d. Operating Configuration B. POSITIONING Positioning the Jarraff while cutting is very important. With the trees on the left side of the Jarraff, uncut limbs do not hinder the operator s vision. And the saw motor does not get caught in the tree or cut tree limbs. IMPORTANT: Operating the Jarraff beyond a 25 slope is not recommended. It is important to stay out of the red zone on the inclinometer, while operating the Jarraff on a slope or hill side. C. TRAVELING When the ground conditions are good and the terrain relatively smooth, it is not necessary to cradle the boom while moving the Jarraff. The boom may be retracted and lowered to a position not interfering with advancing to the next set. This allows for almost continuous cutting, however if ground conditions are poor and terrain is rough, the boom may be cradled in a matter of seconds. After the boom is cradled a slight down pressure will ensure that the boom will not bounce up and down while in the cradle position. D. CUTTING 1. Cutting Quadrants When cutting, the saw blade may be operated from all quadrants of the Jarraff. Optimum cutting speed is obtained when cutting over the left corner of the Jarraff. Which corresponds to the operator s left hand side Cutting Sequence Maximum production is attained when the operator is free to use all of these cutting strokes. A typical cutting sequence is as follows: the boom is raised and extended to cut the nearest low limb. This gives the operator a point of reference for the rest of the limbs to be reached. With the next cut, an up and out stroke cuts the next limb. Repeat the procedure until all the limbs within reach are cut. The Jarraff is then advanced to the next set of cuts.

58 5. A. Appendix - Fiberglass Boom Cleaning Fiberglass Boom Cleaning and Waxing Procedure -Position the vehicle unit on solid ground adjacent to a water supply -Remove boom inspection plates and covers. Elevate booms slightly for drainage. -Wash booms using lint-free cloth, a garden hose and 40 PSI maximum water pressure. No pressure washers or steam cleaners should ever be used on the fiberglass booms. -For stubborn contamination, products designed for fiberglass products should be used. American Polywater, Rexco, Hastings Fiberglass, Donar Chemicals and Kearney all offer such products. -Raise booms to full height possible and leave upright for 1-2 hours to allow excess moisture to drain from booms and for air to circulate through booms. Allow longer time if possible. Isopropyl alcohol may be poured into the boom to clean and flash moisture remaining. The alcohol is mild enough not to damage the fiberglass boom or any components inside. -Lower boom and wipe/dry booms external and using inspection holes, internal surfaces and components (hoses, leveling rods, air lines, etc) to speed the drying process. -Garage vehicle overnight with the booms raised as high as the garage roof allows. -Leave boom inspection covers and cap open or removed to allow air circulation. -Ensure garage is heated overnight. A fan may also be used to direct hot air up and through the boom structure. -The following morning carry out a visual check of inspection for signs of water/moisture inside the booms. Clean any visible dirt from hose etc, Inside booms. -Once the fiberglass boom is clean, it should be coated with a product designed to protect its surface. The aforementioned companies also offer good wax products designed for use on fiberglass to protect the boom s glossy surface and maintain a barrier against dirt, grease, creosote, etc. Some manufacturers may not recommend waxing, particularly telescoping booms. -After the booms have been cleaned, dried and waxed a dielectric test should be performed in accordance with ANSI A92.2 Section 5.4.3, to assure dielectric integrity. If the booms fail, allow more drying time and test again. -When the booms pass, replace all inspection covers and guards. 58

59 - If during the inspection or cleaning process you discover chips, chaffs or abrasions that may allow moisture to find its way into the fiberglass of the boom, the surface should be recoated or sealed in accordance with the manufacturers recommendations. - This is not intended to replace individual manufacturers recommendations. This is only to be used as a guide. 59
