Subsequent Use of the Generator If this is not your first time using the generator there are still steps you should take to prepare it for operation. IMPORTANT: At this point you should be familiar with the procedures described in the first portion of this section entitled "Using the Generator for the First Time."...
Starting the Generator: Gasoline CAUTION: LPG must be shut off when using gasoline! Gasoline must be shut off when using LPG! Disconnect all electrical loads from the generator before attempting to start! 1. Make sure that the AC circuit breaker is in the OFF position. The generator may be hard to start if a load is connected.
Starting the Generator: Propane CAUTION: LPG must be shut off when using gasoline! Gasoline must be shut off when using LPG! Disconnect all electrical loads from the generator before attempting to start! 1. Make sure that the AC circuit breaker is in the OFF position. The generator may be hard to start if a load is connected.
The surge wattage ability of the generator covers this extra power requirement. Model Number Rated (Running) Wattage Surge (Peak) Wattage XP4400EH 3500 4400 Figure 9 - Generator Wattage by Model Number The total running wattage requirement of the electrical devices connected to the generator should not exceed the rated wattage of the generator itself.
Using the Generator (Continued) Once you have found the rated wattage requirement of each electrical device, add these numbers to find the total rated wattage you wish to draw from the generator. If this number exceeds the rated wattage of the generator, DO NOT connect all these devices. Select a combination of electrical devices, which has a total rated wattage lower than or equal to the rated wattage of the generator.
Page 17
Connecting a Load to the Generator NOTE: Be sure to attach devices to the correct receptacle (outlet). 120v devices can be directly connected to the 120v ONLY receptacles. 120v devices can be connected to the 120/240v receptacle using an appropriate adapter.
Page 18
Choosing the Right Power Cord Long or thin cords can drain the power provided to an electrical device by the generator. When using such cords, allow for a slightly higher rated wattage requirement for the electrical device. See Figure 12 for recommended cords based on the power requirement of the electrical device.
MAINTENANCE AND CARE The Importance of Maintenance Proper routine maintenance of your generator is essential for safe, economical, and trouble-free operation. It will also help reduce air pollution. Warning Improper maintenance, or failure to correct a problem before operation, can cause a malfunction in which you can be seriously injured or killed.
figure 13. When the oil level is low you will need to add oil until the level is sufficient to run the generator. The oil capacity of your generator engine is listed in figure 15. Model Number XP4400EH Engine Oil Capacity 20 fl. Oz.
Changing the Oil It is only necessary to drain the oil from the crankcase, other than for regular oil changes, if it has become contaminated with water or dirt. In this case, you can drain the oil from the generator according to the following steps: 1.
Air Cleaner Maintenance Routine maintenance of the air cleaner helps maintain proper airflow to the carburetor. Occasionally check that the air cleaner is free of excessive dirt. 1. Unhinge the clasps at the top and bottom of the air cleaner cover (see figure 18).
Spark Plug Maintenance The spark plug is important for proper engine operation. A good spark plug should be intact, free of deposits, and properly gapped. To inspect your spark plug: 1. Pull on the spark plug cap to remove it. 2.
Storage and Transportation CAUTION: Never place any type of storage cover on the generator while it is still hot. When transporting your generator: Empty the gas tank (see "Emptying the Gas Tank" in the "Maintenance" section). Disconnect the spark plug. Do not obstruct any ventilation openings.
