Wacker Neuson 3503 Track Excavator Operators Manual

Towing the Wacker Neuson 3503 track excavator
Towing the machine is not recommended. Damage to the machine may occur. If the machine must be towed, follow the guidelines and procedures below:

1. Make sure the excavator can be towed safely.
2. Use towing bracket A for towing the machine.
3. Do not use towing bracket A to tow another machine, other equipment, or trailers.
4. Secure clevis B with the clevis pin and a lock pin.
5. Mount a towing bar or cable of adequate size to the towing bracket.
6. Make sure no one is close to the towing equipment (towing bar, cable).
7. Do not jerk the machine.
8. When towing the machine, do not exceed the maximum operating speed of the excavator. – see 2 speed ranges on page 6-2

Lifting excavator, Load the machine as follows:

• Fit the standard bucket and lock it safely.
• Empty the standard bucket.
• Tilt in the standard bucket..
• Stop the engine.
• Fold the control lever base up.
• Remove the starter key.
• Do not allow anyone to stay in the cab, and close the doors and the engine cover.
• Use suitable lifting gear, tracks etc.
• Mount the lifting gear at the point on the boom provided for lifting the machine.
• Mount the lifting gear at the points on the stabilizer blade provided for lifting the machine.
• Make sure the lifting gear has the required lengths L1 and L2.
• Slowly raise the machine

Operating Wacker Neuson 3503 Track Excavator
Upper carriage hydraulic brake:
The upper carriage's rotation is sufficiently braked by moving control lever 1 back to the neutral position. Moving the control lever in the opposite direction (counteraction) brakes the upper carriage with maximum hydraulic output.

Upper carriage mechanical brake:
This is a multi-disk mechanical brake that provides a secondary service brake and a primary parking brake function for the upper carriage. It is operated independently from the hydraulic brake of the upper carriage.

Control lever with proportional controls (option): overview
This control mode offers proportional operation of the auxiliary hydraulics circuit depending on the position of slide switch B on the joystick. You can also modify the properties of the characterisitic curve. Precision work, for instance with the offset bucket, does not require the full throughput of the auxiliary hydraulics. Therefore we recommend setting the controls to the low characteristic curve 1 (slow movements). The slide switch is not pressed fully in this position and you can move the machine more smoothly (flat characteristic curve).
