Hi can anyone help. I use an electric wheelchair to get around and can only walk a few steps with a wheeled walker. Yesterday I went to my local out of town ASDA, a 1.5 mile trip approx through an alley/Public Footpath, I have done this many times before. This time I was about 3/4 of the way there and the chair started to judder and slow down and pull to the right. It then stopped and after a quick look the right hand motor was hot enough to literally blister my finger whilst the left hand one was touchably warm. I waited for a while and the chair switched on and moved a short way (100mtrs or so) then started to judder again, so I stopped again. My only thought was to get to ASDA and get help so I looked in the backpack on the chair in the hope of finding something to cool it down like a forgotten water bottle. All I found was a 500 ml bottle of Oilatum ( a liquid paraffin skin treatment) I poured half of this over the motor and waited for 1/2 hr and then poured the rest of the liquid over it to cool it even more so I could get to the supermarket and get help. I got to ASDA and the motor was much cooler. I went to the cafe and turned it off for an hour and then switched on and did my shopping, checking the temp of the now cool motor every few mins. It did not overheat so I continued my homeward journey, the motor stayed at the same temp as the other one and did not get hot even though the return journey is more uphill. Does this mean the motors need lubrication or was this coincidence?
