  • Page 11 Section I - SAFETY PRECAUTIONS (cont'd) SAFETY TIPS Death or serious injury can occur when working near power lines. Learn - beforehand - as much about your working area as possible. Be sure that exact locations of overhead power lines, and other obstructions or hazards are known.
  • Page 12 Section I - SAFETY PRECAUTIONS (cont'd) SAFETY TIPS Proper technique for using wire rope clips. USE CABLE CLIPS ONLY IN THE EVENT OF AN EMERGENCY FIELD TEMPORARY REPAIR. RIGHT WRONG 1. Turn back rope length specified in the chart. Apply first clip so U-bolt is no less than the saddle width from the dead end. Tighten nuts evenly and torque as specified.
  • Page 13 Section I - SAFETY PRECAUTIONS (cont'd) SAFETY TIPS Don't use a wrecker that has not been properly maintained. Pay special attention to wrecker mounting bolts, cable condition, and lubrication of moving parts. Don't use damaged cables on your wrecker. Become familiar with the various types of cable damage and carefully inspect all cables being used in a recovery operation before...
  • Page 14 Section I - SAFETY PRECAUTIONS (cont'd) SAFETY TIPS Don't expect your wrecker to tow loads equal to the wrecker rating. Wrecker ratings apply to loads imposed during recovery, with the wrecker properly stabilized. Don't pull a load with your wrecker without making absolutely sure that the winch drum clutch is FULLY engaged.
  • Page 15 Section I - SAFETY PRECAUTIONS (cont'd) SAFETY TIPS Don't get under a raised vehicle or load unless it has adequate safety blocks in place. Don't exceed WORKING LIMIT ratings of cable. Use breaking strength ratings only for selecting replacement cable. Don't tie down the front end of your wrecker for recovery work or heavy lifts.
  • Page 16 Section I - SAFETY PRECAUTIONS (cont'd) SAFETY TIPS Don't lower outboard legs or rear spades unless area under them is clear. Pay particular attention to keeping this area clear. Don't use rear spades on paved surfaces unless you are willing to accept responsibility for possible damage to such surfaces.
  • Page 17 Section I - SAFETY PRECAUTIONS (cont'd) SAFETY TIPS Don't completely unwind all cable from a winch while loaded. Keep AT LEAST five wraps on the drum. Don’t operate your wrecker ’s engine faster than recommended. Excessive speeds can damage PTO shafts, hydraulic pumps and winches. Don’t rely on anti-theft steering locks.
  • Page 18 Section I - SAFETY PRECAUTIONS (cont'd) SAFETY TIPS Don't use towing forks that are not of proper size for pick-up requirements. After you have hooked up a vehicle for towing, don't start the tow until you have double checked the hook-up, installed safety chains and released the parking brakes on the towed vehicle.
  • Page 19 Section I - SAFETY PRECAUTIONS (cont'd) SAFETY TIPS Don't tow a vehicle on its front wheels if they are damaged. Don't tow a vehicle on its front wheels unless the steering wheel is secured with the front wheels straight ahead. Don't tow a vehicle at night without proper signal lights on the towed vehicle and the wrecker.
  • Page 20 Section I - SAFETY PRECAUTIONS (cont'd) SAFETY TIPS Don’t move wrecker or extend boom where overhead power lines may be encountered. Don’t continue to wind in winch cable after the hook is against the boom end. SAFE TOWING There are two key factors in safe towing: 1. Have enough front axle weight for safe steering.
  • Page 21 Section I - SAFETY PRECAUTIONS (cont'd) SAFE TOWING To use the formula, multiply the unladen weight at the front axle by .5. Multiply the result by the wheel bases. Then, divide that result by the overhang. So, you should calculate the maximum lifted load for each tow truck, using this formula, post those limits in the truck and instruct each driver to strictly observe those limits. You should also observe gross vehicle weight ratings (GVWR), gross axle weight ratings (GAWR), and the towing equipment ratings.

  • Page 66 Section V - MAINTENANCE (cont'd) 5.8 FILTER/REGULATOR OPERATION AND SERVICE (cont'd) 5. Replace bowl gasket; lubricate gasket to assist in retaining it in position. Use only mineral base oils or grease. Do NOT use synthetic oils such as esters, and do NOT use silicones. 6. Screw bowl into body and tighten firmly. (g) The regulator may be serviced without removing it from the line. Before disassembling filter/regulator, SHUT OFF AIR SUPPLY AND EXHAUST PRIMARY AND SECONDARY PRESSURE. Disengage the adjusting knob by pulling upward. Turn the adjusting knob counterclockwise until compression is released from pressure control spring.
  • Page 67 Section V - MAINTENANCE (cont'd) 5.9 LUBRICATOR OPERATION AND SERVICE (a) FILLING - Inlet pressure must be eliminated before the fill plug or bowl is removed. Fill to fill line on the bowl (DO NOT OVERFILL) with oil of 100 to 200 SSU viscosity at 100° F and an aniline point greater than 200° F - same as SAE No. 10 (petroleum base hydraulic oils are good examples). DO NOT USE OILS WITH ADHESIVES OR TACKY ADDITIVES. COMPOUNDED OILS CONTAINING SOLVENTS, GRAPHITE, SOAPS OR DETERGENTS (automotive oils generally contain detergent) ARE NOT RECOMMENDED. (b) Replace the fill plug and/or bowl assembly firmly - excessive torque is not necessary. The lubricator is now ready for setting. Repressurize the lubricator.
