+ My chain saw does not start and the chain does not move.
Check to see if the safety chain brake lever is engaged. To reset the chain brake, disconnect the tool from the mains and snap the chain brake lever backwards (towards the operator).
+ What type of oil does my unit take?
Your Sun Joe iON Chainsaw uses regular Bar and Chain Oil, available for purchase on our website under model number SWJ-OIL.
+ How long does the battery for my Sun Joe iON16CS Chain Saw take to charge?
Your Sun Joe iON16CS Chain Saw comes with a 40-volt EcoSharp® lithium-ion battery charger (Model# iCHRG40) that completely charges your battery in up to 2 hours.
+ How loud is my Sun Joe iON16CS?
Your Sun Joe iON16CS has a decibel rating of 90 dB.
To better understand this noise level, please refer to this chart for means of comparison:
+ How does a brushless motor compare to a traditional motor with brushes?
The iON16CS is equipped with a 600 W brushless motor. Without going into an engineering lesson, brushless motors are smarter, more powerful and more efficient than their old school brushed cousins. So when comparing cordless devices, you can’t just compare voltage. A lower voltage brushless motor is far better than a higher voltage, old school brushed motor. So a new cordless unit with a brushless motor will mean that it can perform better and last longer on a charge than a comparable unit with a traditional cordless motor.
+ How long will the battery in my Sun Joe iON16CS Chain Saw run for?
Your Sun Joe iON16CS Chain Saw comes with a 40-volt 4.0 Ah lithium-ion battery (Model# iBAT40) that delivers up to 45 minutes of whisper-quiet run time.
+ What is the best measurement of a lithium-ion battery pack’s performance? How does the Snow Joe + Sun Joe EcoSharp 40 V 4.0 Ah lithium-ion battery pack (model iBAT40) compare to other lithium-ion battery packs in the market?
Without getting too technical, the best measure of a lithium-ion battery pack’s performance is its energy capacity, which is measured in watt-hours. To find the watt-hours of a battery pack, multiple the voltage by the amp-hours. For example, the Snow Joe iON18SB 40 V 4.0 Ah 18-inch cordless snow blower runs on a lithium-ion battery that delivers a 160 watt-hour energy capacity (40 V x 4.0 Ah). In comparison, competitor models of cordless tools that also employ a 40 V lithium-ion battery may only be telling you half the story. They cleverly disguise a seemingly “more powerful” battery pack by tacking on a large voltage rating without disclosing the amp-hour rating information, which has been found in some cases to be, at best, only 2.6 amp-hours. A battery with the same voltage rating, but a lower amp-hour rating will have a lower energy capacity, which will significantly impact your cordless tool’s performance. Comparing the Snow Joe + Sun Joe EcoSharp 40 V 4.0 Ah lithium-ion battery pack to the 40 V 2.6 Ah competitor lithium-ion battery pack, the EcoSharp battery provides about a 1.6 fold increase in energy capacity (160 watt-hours versus 104 watt-hours). So, when comparing battery packs, it’s not only voltage that matters in terms of cordless tool performance. Know your battery’s amp-hour and watt-hour rating to get a true assessment of what your battery can really do.
+ Can the EcoSharp 40 V 4.0 Ah battery pack (model iBAT40) and the EcoSharp PRO 40 V 5.0 Ah battery pack (model iBAT40XR) be used interchangeably with all iON tools?
Yes, both the EcoSharp 40 V 4.0 Ah battery pack (model iBAT40) and the EcoSharp PRO 40 V 5.0 Ah battery pack (model iBAT40XR) can be used with all iON and iON PRO series tools. Both batteries also utilize the same 40 V EcoSharp charger (model iCHRG40).
