Ryobi OLM1840BL Questions & Answers

I tried all of the troubleshooting mentioned in the manuals / forums and youtube.., unfortunately none of these work. I had to take it back to the vendors where i bought it off from., they tried everything with fresh pair of batteries even., they could not get it to work..., i could not get any solution for this..., so got my purchase refunded.

You can try the following by..apparently it did not work for me. I had same problem but after 3 months of purchase.. seems like a common fault with the model. STEPS 1. Retracting the handle again. Check if the handle is fully extended. 2.readjust the cutting height 3.Check if the mulcher plug is correctly inserted,reinsert it. 4. Take out the batteries 5. Take out the key 6. After half hour ..,Reinsert key then batteries.

Thank you I’ll try that

I have the Ryobi 40v (6 amp) 20" electric mower and, after storing it away (properly) for the winter, had hoped to start 'er up and clean up the fresh spring grass today but she wouldn't start. I tried everything. Everything. Turns out this model has TWO, count 'em two (2), battery slots: one for the power, one for a spare. I had the battery in the spare compartment which has no power connection. Finally, switched it to the front slot and she works great. Boy, do I feel stupid.

You may want to contact Ryobi, as I haven't heard of this happening. Unless your Battery is flat. Thick grass should really be trimmed with a whipper Snipper first.

I am having similar issues without even trying to cut thick grass, to the point where the mower won't even start when sitting on the pavement. This is with 2 x 6aH HP batteries, fully charged.

Same thing with mine. Half way through mowing the lawn and stopped, at first I thought it was the battery but swapped out for two fully charged batteries and won’t start with green lights changing to red flashing lights. Any ideas? Is only a few months old

i experienced the exactly same thing just recently., Just wondering if this a faulty product that we have been sold in to. I bought it from Bunnings Marsden last year in Nov, They still have quite a few in stock. i think i have used 5-6 times all throughout now it does not start. Even after installing freshly charged ryobi batteries 18volts., 6 amps. Pressing the switch and then the handle bar throttle., the light goes from green to red.

I have the same issue. Answer Solutions? Only 2 months old. Used 8 times only

We are having the same problem - I have reached out to Ryobi, awaiting a response. If anyone has found a solution, please let us know!

Update 7/5/22: Took it to Bunnings, said it wouldn't start and they replaced it with a new one no questions asked. Warranty reset when registered with Ryobi.

My local Bunnings actually has it in stock in the store, but just not listed on Bunnings' site.

The model OLM1840BL, which seems the same, is available at Bunnings in AU & NZ this one does not come with any battery.

It still on Ryobi Australia website but I just check Bunning and they don't seem to have it anymore. Not sure if it is the stock issue or marketing reason. Ryobi had 36v mower using two 18v batteries before, but they cut it away to force user to buy the 36v system.

c/o manual pg4 "NOTE: The flashing red LED in the LED fuel gauge indicates mower overload." It appears that the LEDs flash when the batteries are flat also. The 6Ah Ryobi batteries have a 'check charge' button on the front * "For best performance, always cut off one third or less of the total height of the grass." (pg4) at a time * Remove the batteries (for safety) then check for tangled grass around the shaft, clear with a brush - not water (pg20) * Install both batteries (latches should click) for greater cutting power. (pg11) * Check isolator key is seated in the battery housing (pg 11)

I have a manual thanks

I posted this on Ryobi's facebook page and the answer is yes to both

Sure can. There is an insert (which comes pre-installed) which is used for mulching.
