QUIETER OPERATION
Exclusive Quiet Armor™ technology ensures 20% LESS NOISE than leading commercial-grade portable generators
THE TRUTH BEHIND DECIBEL RATINGS
Not all generator brands use the same testing standards to determine decibel ratings, meaning advertised ratings are hard to compare from brand to brand. NorthStar sets the record straight.
HEAD-TO-HEAD TESTING
An independent sound laboratory put the new NorthStar commercial-grade generators with Quiet Armor™ technology to the test against the leading generator brands using identical testing methods. Test results revealed the NorthStar commercial-grade generator is significantly quieter than the competition.
BUILT STRONGER
Made to last with HEAVY-DUTY steel frames, HIGHEST-QUALITY components and backed by the BEST warranties on the market
EASIER TO USE
Conveniently MONITOR ALL generator functions on one easy-to-read LCD display
MORE EFFICIENT
Electronic fuel injection provides CONSISTENT STARTING, uses LESS FUEL and provides MORE POWER
BETTER EQUIPPED
Full panel of GFCI outlets provide ESSENTIAL jobsite SAFETY and CONVENIENCE

How do you change the oil? What's the best oil to use?
1 answer-
NorthstarExpert12· a month ago
This generator uses SAE 10W-30 oil for operation in temperatures above 32°F. For temperatures below 32°F, SAE 5W-30 oil is recommended.
To change the oil, follow these steps:
1. Drain the oil when the engine is warm to ensure quick and thorough draining.
2. Unscrew the oil fill port and oil drain bolt to drain the oil. Replace the oil drain bolt and tighten it.
3. Refill the reservoir with the recommended oil and check the oil level.
4. Reinstall the oil fill port.

NorthstarExpert12· 11 months ago
This generator should never be placed inside a box, it requires a minimum clearance of 7 feet. This generator is equipped with a CO sensor. At this time, we do not offer a generator that is recommended to be placed inside a box during operation.
