PACKAGE CONTENTS Your generator comes with the items listed below. Please check to see that all of the following items are included with your generator. Double Sided Screw Driver Spanner Spark Plug Wrench Phillips and slot blade screwdriver used for generator maintenance. Assorted wrenches used in generator maintenance and assembly. Commonly 8mm, 12mm Used in spark plug maintenance, inspection, and installation.
GENERATOR SETUP Proper setup of your generator will get you going as soon as possible while making sure you and your equipment are safe and cared for.
GENERATOR SETUP (CONTINUED) Step 1 - Connect the Battery 1. Remove the battery cover a. Remove the battery cover plate by removing the screw. 2. Connect the negative cable a. Push the black rubber boot up the wire to expose the connector. b. Securely connect the free end of the battery cable to the negative battery terminal using the screw and nut from the battery with the screwdriver and wrench from the toolkit. 3. Reinstall the battery plate 22 a.
Step 2 - Adding Oil The generator requires engine oil to operate properly. The generator, when new from the package, contains no oil in the crankcase*. You must add the proper amount of oil before operating the generator for the first time. This amount is equal to the oil capacity of the engine crankcase: Model Number XP4500iH Engine Oil Capacity 20 fl. oz (0.6L) WARNING: Do not apply engine oils with additives or 2-stroke gasoline engine oils.
GENERATOR SETUP (CONTINUED) Step 3 - Adding Gasoline (Optional) Add Gasoline a. Make sure the generator is on a level surface. b. Unscrew gas cap and set aside (NOTE: the gas cap may be tight and hard to unscrew). c. Slowly add unleaded gasoline to the fuel tank. Be careful not to overfill. The fuel gauge on the top of the gas tank indicates how much gasoline is in the generator gas tank. d. Replace fuel cap and wipe up any spilled gasoline with a dry cloth.
Step 4 - Grounding the Generator Attach grounding wire a. Ground the generator by tightening the grounding nut against a grounding wire. b. Connect the other end to a copper or brass grounding rod that’s driven into the earth. A generally acceptable grounding wire is a No. 12 AWG (American Wire Gauge) stranded copper wire. Grounding codes can vary by location. Please contact a local electrician to check the grounding regulations for your area.
STARTING THE GENERATOR If this is not your first time using the generator there are still steps you should take to prepare it for operation each time you use it. IMPORTANT: At this point, you should be familiar with the procedures described in the first portion of this section entitled “GENERATOR SETUP” If you have not yet read this section, go back and read it now.
BEFORE YOU START YOUR GENERATOR Step 1 - Check the oil Check the oil The generator is equipped with an automatic shutoff to protect it from damage due to low oil. Nonetheless, you should check the oil level of the engine before each use to ensure that the engine crankcase has a sufficient amount. To check the oil level: 28 a. Make sure the generator is on a level surface. b. Remove the oil cover. c. Unscrew the oil filler/dipstick cap. d.
Step 2 - Check the gas level (Optional) Check fuel level If running the engine on gasoline check to see that there is sufficient gasoline in the fuel tank. The fuel gauge on top of the tank will give a rough estimate of the gasoline level. The gauge will appear white then fill red as the tank is filled. Note: Fuel gauge may not register with less than 1/3 fuel tank full. DANGER 1.5” DO NOT OVERFILL THE GAS TANK OVERFILLING CAN RESULT IN A FIRE, EXPLOSION, OR DEATH.

MAINTENANCE LOG Date Generator Hours Maintenance Performed 47
MAINTENANCE AND CARE (CONTINUED) Checking the oil Check the oil The generator is equipped with an automatic shutoff to protect it from damage due to low oil. Nonetheless, you should check the oil level of the engine before each use to ensure that the engine crankcase has a sufficient amount. To check the oil level: 48 a. Make sure the generator is on a level surface. b. Unscrew the oil filler/dipstick cap. c. With a dry cloth, wipe the oil off of the stick on the inside of the cap. d.
Changing the oil Worn out or dirty oil does not cool the generator properly and can lead to catastrophic engine damage. In addition to regular oil changes, it is necessary to drain the oil from the crankcase if it has become contaminated with water or dirt. 1. Remove drain cover Remove the oil drain covers. Then using a 12 mm hex wrench, unscrew the oil drain plug, which is located on the crankcase underneath the oil filler/dipstick cap. Allow all the oil to drain from the generator. 2.
MAINTENANCE AND CARE (CONTINUED) Cleaning the air filter Routine maintenance of the air cleaner helps maintain proper airflow to the carburetor. Check that the air cleaner is free of excessive dirt after every use. Note: Improper maintenance may cause less air to enter the engine or dirty air to enter the engine causing overheating and engine wear. 1. Remove the filter cover Release the clip on the top of the cover and move the filter cover to allow access to the element. 2.
4. Dry cleaner element Pat dry on a dry cloth and allow the elements to dry completely. 5. Add engine oil to elements Soak the dry elements in a small amount of engine oil. Ring out any excess oil. 6. Replace elements in casing Replace the sponge-like elements in the air cleaner casing and replace the cover.
MAINTENANCE AND CARE (CONTINUED) Spark Plug Maintenance SPARK PLUG CONSULT MANUAL BEFORE REMOVING The spark plug is important for proper engine operation. A good spark plug should be intact, free of deposits, and properly gapped. Improper maintenance may cause reduced fuel economy, misfires, trouble starting, or damage to the spark plug threads. 1. Remove spark plug cap Pull on the spark plug cap to remove it. 2.
4. Measure plug gap Measure the plug gap with a gauge. The gap should be 0.7-0.8 mm (0.028-0.031 in). 5. Clean and re-gap If you are re-using the spark plug, use a wire brush to clean any dirt from around the spark plug base and then re-gap the spark plug. 6. Install spark plug Screw the spark plug back into its place on the generator using the spark plug wrench. 7. Replace spark plug cap Replace the spark plug cap.
MAINTENANCE AND CARE (CONTINUED) Storage and Transportation CAUTION: Never place any type of storage cover on the generator while it is still hot. When transporting your generator: ● Disconnect the spark plug. ● Do not obstruct any ventilation openings & keep the generator in a cool dry area. Storage Period Storage Preparation If you plan on starting the same day. 1. 2. 3. 4. Turn off the main breaker. Allow the unit to run 3 - 5 minutes. Turn off the start switch. Store.
