Safety Information GP/GPS 6600A Label Meaning DANGER! No sparks, flames or burning objects near machine. Shut off the engine before refueling. Read the Operator’s Manual for machine information. WARNING Operation of this equipment may create sparks that can start fires around dry vegetation. A spark arrestor may be required.
Check with your nearest Wacker Neuson dealer, or contact the manufacturer or dealer of the tool or appliance, with questions regarding its power requirements.
Operation GP/GPS 6600A Installation Place the generator in an area where it will not be exposed to rain, snow, or direct sunlight. Make sure it is positioned on firm, level ground, so it will not slide or shift. Position the engine exhaust away from areas where people may be present.
GP/GPS 6600A Operation Battery 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. 3.4.3 Insert the nuts (c) onto the screws and tighten.
Operation GP/GPS 6600A 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.
Operation GP/GPS 6600A 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.
GP/GPS 6600A Operation Grounding the Generator A ground connection (a) is located on the generator frame. For proper operating safety, this ground terminal must be connected to a good ground source. This ground connection must comply with National Electrical Code standards, and state and local regulations. wc_gr000544 Operating Heavy Loads Limit operations requiring the maximum rated output of 6600 W to 20–...
Operation GP/GPS 6600A 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.
Operation GP/GPS 6600A 3.11 Ground Fault Circuit Interrupter (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”...
GP/GPS 6600A Operation 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 approximately 7 seconds after all appliances or tools attached to the...
Operation GP/GPS 6600A 3.15 Voltage Selection The voltage selector switch (e) allows the generator to operate in either single (120V) or dual voltage (120/240V) mode.
