Questions & Answers

I need to replace my 5 "adhesive disk to a hook & Loop type
Phil for model number DW420

How do I find out if I have a model 1 or 2
Phil for model number DW420
Hi Phil, you are looking for the type number, "Type numbers" go by different names, depending on the manufacturer. Some manufacturers call them type numbers, while sometimes they are called the: engineering number, series number, or bar code number. Type numbers can be very difficult to find, sometimes located on the inside of a tool's housing (like some Ryobi tools). Fortunately, most type numbers are listed on the name plate with the model number. When a manufacturer does not anticipate redesigning a tool or machine model, the first type of that model often does not have a type number assigned to it by the manufacturer. Designs that follow the first type will usually have type number designations. Thank you for your question and good luck with your repair!

Question: Dw420 Slow

utester

My sander has been slowing when it gets hot. I can squeze the housing and it speeds up. any cures for this?
open the housing ,change the brushes.
Brushes and cord were replaced recently. Could it be a bad connection ?
[QUOTE=utester;7970]My sander has been slowing when it gets hot. I can squeze the housing and it speeds up. any cures for this?"

Open top cover. Check screws on each side of the bearing for security.
WJA
You may want to check your bearings, even though they are sealed, fine saw dust will penetrate the seal and tighten up a bearing.
