3. The Boxer has one saddle fuel tank (Item 1, Figure 3–2). The tank has a fuel gauge (Item 3, Figure 3–2) located in the filler cap (Item 2, Figure 3–2). Remove cap and visually inspect fuel level to make sure that the indicator is showing the proper fuel level. Make sure that the tank has been filled on a daily basis. Carefully add fuel. EF 3 1 2 Figure 3–2 Fuel Level Check 4. Check all hydraulic hoses, lines and fittings. Pre-Start Inspection and Operation WARNING Hydraulic oil under pressure can penetrate body tissue causing serious injury and possible death. When troubleshooting a hydraulic system for leaks, always use cardboard or wood as a detector. DO NOT USE YOUR BARE HANDS. If you are injected with hydraulic oil or any other fluids, immediately seek treatment by a doctor trained in the treatment of penetrating fluid injuries. • Visually inspect all of the hydraulic hoses, lines and fittings for signs of damage, wear or leaking. • If any signs of damage are visible, do not operate the machine until repairs have been made. • Some examples of common hydraulic hose damage are shown in Figure 3–3. 1 3 4 2 Figure 3–3 Hydraulic Hose Damage 1. End fittings damaged or leaking 2. Outer covering chafed or cut, and wire reinforcing is exposed 3. Hose shows signs of kinking or crushing 4. Outer covering ballooning 5. Check for loose or missing fasteners • Inspect for any loose or missing bolts. • Tighten or replace any missing bolts immediately. 6. While you are performing the daily maintenance, inspect the machine for any signs of damage, such as missing or damaged components, cracked welds, etc. 7. Check the track assemblies to make sure that: • The tracks are in good condition and are not showing any signs of wear. • Track tension is properly set. • Track drive motors are not leaking oil or hydraulic fluid. Pre-Start Inspection and Operation 8. Grease pivot shafts with proper type of grease. There are 5 grease points on this machine, see Figure 3–4. NOTICE The grease zerk below the chain tension bolt should only be greased monthly. Figure 3–4 Grease Zerk Locations Pre-Start Inspection and Operation CAUTION Before starting the engine: • Move all hydraulic control levers forward and release the lever. Make sure that each lever automatically returns to the Neutral position. • Move all hydraulic control levers rearward and release the lever. Make sure that each lever automatically returns to the Neutral position. • Step on the operator presence control and shift the Trencher Control Lever to the right into the trenching position. The control lever should remain in that position as long at the dead man control is held down. Releasing the operator presence returns the Trencher Control Lever to the neutral position. • If any of the levers, other than the Trencher Control Lever, does not automatically return to the Neutral position, DO NOT use the machine until repairs have been completed. NOTICE Extremely dusty or dirty working conditions may require more frequent service/replacement. 3-7 Pre-Start Inspection and Operation Operating Instructions Machine Start-up To start the machine, the operator must: 1. Stand on the operator's platform (Item 1, Figure 3–5). 2. Move the throttle lever (Item 2, Figure 3–5) to about half way between fast and idle engine speeds. 3. Move the engine choke lever (Item 3, Figure 3–5) to the CHOKE position. 4. Rotate and hold the starter switch (Item 4, Figure 3–5) in the START position until the engine starts. Figure 3–5 Operator's Platform, Engine Throttle, Choke and Key Switch 5. As soon as the engine starts, release the starter key. The key will automatically return to the RUN position. 6. Leave the throttle setting at about the halfway position and allow the engine to idle. This will begin warming the hydraulic oil. 7. If the engine begins to labor or sputter, move the choke control lever to the normal run position. It may be necessary to move the choke lever only part way to the normal position until the engine has warmed up. 8. In cold weather (32. F [0. C]) after about 5 minutes of engine idling, operate all of the main hydraulic controls to cycle warmed hydraulic oil through the hydraulic lines into the cylinders and hydraulic motors. Allow the engine to idle for another 5 minutes before beginning any machine operations. 3 2 1 4 2445 3-8 Pre-Start Inspection and Operation In extremely cold weather fully warm machine to prevent a possible machine run-away condition. Machine Shut-down To safely shut the machine down, the operator must: 1. Park the machine on a solid, level area. 2. Lower the trencher boom to the ground. 3. Idle the engine for 5 - 10 minutes to allow the machine to cool down. 4. Shut off the engine. 5. Clean off any accumulated mud and/or dirt from the machines operating surfaces, i.e. operator’s platform, both track assemblies, trencher chain assembly, etc. Transportation 1. Move the throttle control lever to the mid-range engine speed. Raise the boom so that it w...
