3.  Release fastener lever to secure end of strip. 

4.  Begin  wrapping  abrasive  around  drum.  The 

tapered  edge  of  strip  end  should  follow  as 
closely as possible to edge of drum. 

5.  Continue to wrap abrasive in spiral fashion by 

rotating  drum  with  one  hand  and  guiding  strip 
with the other. See Figure 5-5.  

Successive windings of strip must 

not have any 

overlap.

  They  should  be  flush  with  previous 

windings or with a slight gap between.  

 

Figure 5-5 

6.  Press  inboard  take-up  lever  (Figure  5-6)  and 

insert trailing end of strip as far as it will go. If 
necessary, trim tapered end of abrasive strip. 

7.  Release inboard take-up lever to secure strip. 

All abrasive strips will stretch over time as they are 
used, and may stretch enough to allow the take-up 
lever  to  reach  its  lowest  position  so  that  it  cannot 
maintain  tension  on  the  strip.  If  this  occurs,  follow 
the above procedures to reset the take-up lever.

  Electrical connections 

 All electrical connections must 

be done by a qualified electrician in compliance 
with  all  local  codes  and  ordinances.  Failure  to 
comply may result in serious injury. 

The JWDS-1020 Sander is rated at 115-volt power 
only.  The  sander  comes  with  a  plug  designed  for 
use on a circuit with a 

grounded outlet 

that looks like 

the one pictured in Figure 6-1. 

Before connecting to power source, be sure switch 
is in 

off 

position.  

It is recommended that the sander be connected to 
a  dedicated  15  amp  circuit  with  circuit  breaker  or 
fuse. If connected to a circuit protected by fuses, use 
time  delay  fuse  marked  “D”. 

Local  codes  take 

precedence over recommendations. 

6.1

  GROUNDING INSTRUCTIONS 

This machine must be grounded. In the event of a 
malfunction  or  breakdown,  grounding  provides  a 
path of least resistance for electric current to reduce 
the risk of electric shock. This tool is equipped with 
an  electric  cord  having  an  equipment-grounding 
conductor and a grounding plug. The plug must be 
plugged  into  a  matching  outlet  that  is  properly 
installed and grounded in accordance with all local 
codes and ordinances. 

Do not modify the plug provided - if it will not fit the 
outlet, have the proper outlet installed by a qualified 
electrician. 

Improper  connection  of  the  equipment-grounding 
conductor can result in a risk of electric shock. The 
conductor  with  insulation  having  an  outer  surface 
that  is  green  with  or  without  yellow  stripes  is  the 
equipment-grounding conductor.  

If repair or replacement of the electric cord or plug 
is  necessary,  do  not  connect  the  equipment-
grounding conductor to a live terminal.
