Safety Information GP/GPS 6600A Improper connection of generator to a building’s electrical system can allow electrical current from the generator to backfeed into utility lines. This may result in electrocution of utility workers, fire, or explosion. Connections to a building’s electrical system must be made by a qualified electrician and comply with all applicable laws and electrical codes.
GP/GPS 6600A Safety Information 1.3.15 ALWAYS keep the machine at least one meter (three feet) away from structures, buildings, and other equipment during use. 1.3.16 ALWAYS keep the area immediately surrounding and underneath the machine clean, neat, and free of debris and combustible materials. Make sure that the area overhead is clear of debris that could fall onto or into the machine or exhaust compartment.
Safety Information GP/GPS 6600A Operating safety When operating the generator: • Check the fuel lines and the fuel tank for leaks and cracks before starting the engine. • Do not run the machine if fuel leaks are present or the fuel lines are loose.
Page 13
Leaking fuel and fumes are extremely explosive. 1.5.13 When replacement parts are required for this machine, use only Wacker Neuson replacement parts or those parts equivalent to the original in all types of specifications, such as physical dimensions, type, strength, and material.

Labels GP/GPS 6600A WARNING Operation of this equipment may create sparks that can start fires around dry vegetation. A spark arrester may be required. The operator should contact local fire agencies for laws or regulations relating to fire prevention requirements. A nameplate listing the model number, item number, revision number, and serial number is attached to each unit.
3.0.2 Check the machine and its components for damage. If there is visible damage, do not operate the machine! Contact your Wacker Neuson dealer immediately for assistance. 3.0.3 Take inventory of all items included with the machine and verify that all loose components and fasteners are accounted for.
Check with your nearest Wacker Neuson dealer, or contact the manufacturer or dealer of the tool or appliance, with questions regarding its power requirements.
Before using an oxygenated fuel, confirm the fuel's contents. Some states / Provinces require this information to be posted on the fuel pump. The following are Wacker Neuson approved percentages of oxygenates: - (ethyl or grain alcohol) 10% by volume. You may use...
Operation GP/GPS 6600A Battery Tray Installation (GPS only) 3.4.1 Align the holes found in the battery tray (a) to the holes on the frame cross-member 3.4.2 Insert M8 x 14 screws (b) through the tray then through the holes of the cross-member.
GP/GPS 6600A Operation Wheel Kit The wheel kit (Part No. 0161308) is a standard item on Item Number 0620012, 0620015, 0620043 and 0620046 only. It is available as an option on all other models. 3.5.1 Hoist the generator, and align the axle (c) with the lower cross-member of frame.
GP/GPS 6600A Operation Generator Derating All generators are subject to derating for altitude and temperature. Internal combustion engines, unless modified, run less efficiently at higher altitudes due to the reduction of air pressure. This translates into a lack of power and thus reduction in generator output. Temperature affects both engine and generator performance.
Operation GP/GPS 6600A Grounding the Generator Location A ground connection (a) is located on the generator frame. wc_gr000544 Function This ground connection is used for electrically grounding the generator when necessary to comply with the National Electrical Code and other federal, state, and local regulations. For grounding requirements in your area, consult with a qualified electrician, electrical inspector, or local agency having jurisdiction over electrical compliance.
GP/GPS 6600A Operation Use of Extension Cords When a long extension cord is used to connect an appliance or tool to the generator, a voltage loss occurs—the longer the cord, the greater the voltage loss. This results in less voltage being supplied to the appliance or tool and increases the amount of current draw or reduces performance.
GP/GPS 6600A Operation 3.11 Ground Fault Interrupt (GFI / GFCI) The GFCI should be tested for proper operations every time the generator is used. Normal operating state - sensing device green LED is “ON” and circuit breaker is at “ON” position. 3.11.1 Press “TEST”...
Operation GP/GPS 6600A 3.12 Twist-Lock Receptacles Twist-lock receptacles (c, j) are used at the 120V Amp and 120/240V outlets. These receptacles are protected by the GFCI. To attach a power cord to a twist-lock receptacle, insert plug into receptacle and turn it clockwise to lock it in place. 3.13 Engine Auto Idle The auto idle switch (b) automatically reduces engine speed...
GP/GPS 6600A Operation 3.15 Voltage Selector Switch The voltage selector switch (e) allows the generator to operate in either single (120V) or dual voltage (120/240V) mode. In single-voltage mode, use only the 120V twist-lock (c) and duplex receptacles (f1, f2). The full rated power of the generator is shared between the three receptacles.
Operation GP/GPS 6600A 3.16 Before Starting DANGER Carbon monoxide. Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This is a poison you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.
GP/GPS 6600A Operation 3.17.5 On recoil start engines, turn the engine switch to “ON” (b1) and pull the starter rope (f). 3.17.6 On electric start engines, press the ignition switch (k) and hold until the engine starts. Release the switch after the engine starts. NOTICE: DO NOT run the starter motor more than 5 seconds at a time or damage to the starter motor may occur.
Operation GP/GPS 6600A 3.19 Emergency Shutdown Procedure Procedure If a breakdown or accident occurs while the machine is operating, follow the procedure below: 3.19.1 Stop the engine. 3.19.2 Turn off the fuel supply. 3.19.3 Disconnect tools from the machine. 3.19.4 Allow the machine to cool. 3.19.5 Contact the rental yard or machine owner for further instructions.
