User questions & answers

Question:	What is differences/advantages for a variable speed verses a slow speed
Answer:	The advantage to having a variable speed is two fold: The slower speed is generally used for sharpening and honing while the higher speed is for removing material faster and buffing/polishing with a polishing wheel or wire wheel. The slower speed creates less friction and therefore less heat while the higher speed (with a grinding wheel) creates more heat.
Question:	what is the arber size for 8 inch grinder
Answer:	5/8
Question:	How much HP
Answer:	5 amps x 115 volts = 575 watts. 1 hp is around 745 watts, so it works out to be a bit more than 3/4 hp.
Question:	My grinder did not come with the wheel removal tool as it was susposed to. Will someone tell me what size it is so I can remove the bent stone
Answer:	The stone isn't bent, its the mandrel washers that are on both side of the wheel that are not true. Mine are the same way. I tried to contact WEN, never got a response

User questions & answers

Question:	Is this variable speed
Answer:	Rom my experience it is either on or off. If you want variable speed, spend more money!
Question:	I embarrassed I don’t know this, but how do you tighten the arbor bolts? It seems like one loosens the other and there’s no good way to tighten it
Answer:	Don't be embarrassed - one side of the unit has a thread that is the REVERSE of the other. From memory it is the left hand side as you face the unit and so to tighten it you turn the nut as if you were loosening it. The reason is so the spinning motion of the motor doesn't allow the wheel to come loose. Counterintuitive but it works - enjoy!
Question:	How many watts does this take to run
Answer:	The grinder is rated at 6.25 amps, 10 amps would work fine, breakers are rated in amps, not watts...light bulbs are rated in watts.
Question:	How does this model compare to Jets other grinder, model 578008 which seems identical in specs
Answer:	This grinder is a consumer grade while model 578008 is industrial grade. This has small stamped steel wheel flanges while the 578008 has machined wheel flanges. 578008's wheels will always run truer. Published motor specs can be deceiving, this grinder motor is a consumer grade 120 volt motor, the 578008 is an industrial grade motor that is capable of running on either 120 or 220 volts. Run on 220, the motor starts easier and lasts longer. Dust collection equipment is easier to hook up on the 578008's single exhaust exit vs this ones dual oval exits and 578008 is OSHA compliant with an OSHA approved switch. For Me, for the little money more they ask for the 578008 it's a no-brainier go with their industrial grinder model 578008 watch for discounts on the internet, I just picked up the 578008 for 220.00, no tax and free shipping. With tax amazon wanted 277.00

User questions & answers

Question:	is there a 115 volt version available
Answer:	Yes, Although the shafts are short so you will be working close to the housing, unlike the unit designed for buffing.
Question:	Is this thing 220v? Keeps tripping my outlets
Answer:	I sent two of these back. Not only does it trip a GFCI outlet or breaker, but there is serious (and dangerous) current leakage onto the case of the grinder. To test this, I defeated the ground wire and put my voltmeter on the case of the grinder and measured the voltage to ground. While operating the grinder, the voltage on the case ranges from 90 to 150 volts DC depending on speed. You will get a significant shock if you touch it without a functioning ground wire. This is the reason that the GFCI trips - there is significant currant leakage through the case to the ground wire. I consider this to be a serious and dangerous defect, and cannot believe that this machine passed basic UL testing. I would definitely not recommend this grinder until this problem is fixed.
Question:	Can I remove the metal guards and grinding wheels and then add buffing wheels and turn it into a buffer when needed
Answer:	Yes, it would be useful. With the variable speed rheostat it has a wide range of uses. Just have to choose the correct type of wheel for your application. The factory wheels are 40 and 60 grit I believe.
Question:	Why is it tripping my gfa outlets
Answer:	It will take up to a 1" wide wheel.

• 1/2HP dual-speed induction motor with smooth performance and steady torque at both low and high speed. Slow speed is ideal for sharpening edges of woodworking tools, high speed is ideal for quick metal removal
• Includes 80 grit and 120 grit white aluminum oxide wheel which can reduce heat build-up

Question:	what is the horsepower? 1/2, 3/4, 1 hp? Do grinding wheels bought in the USA fit? If not how do you get replacements
Answer:	The labeling on the box says made in PRC. I have 2-8" Jet grinders,and now the metabo 8" all 3 work very well,I use them daily on steel. The important thing is to use american made wheels which are balanced. cheap wheels will make the grinders vibrate, the cheap wire wheels will through the wires, out. You get what you pay for in tools. good luck.
