Re: makita dcs 34 oil not getting to chain bar
Clarification Request Posted by rowdy45176 on Feb 21, 2009 What I would do first is remove the bar and run the saw a short time to see if oil coming out of pump (make sure there is oil in the tank) if so recheck the bar for blockage in the small round hole in the side and run something like a paper clip or small piece of metal to clean out the groove. If you need a breakdown for this tool you might want to try Makitatools.com. I haven't checked to see if it is there but usually it would be. Good luck

remove the chain and bar and try to start without it, if it start then chain was too tight. also you may need to do a small adjustment to carburator. check spark plug gap. check for spark. even brand new one need an adjustment at first use. if you can not make it start it has warranty. take it where you bought it.
Check the oil holes in the bar and the mounting plate to make sure they're not clogged with debris, wood chips, dirt, etc. If the oil ports are clogged, no oil will get through to the bar. If these areas are damaged, you can find a new bar for your saw at Hyperparts.com. Tip: Use the lookup by application (link at the top of the page) with your saw model for an exact fit.
Take the bar and chain off. Clean the engine area where the bar fits to and start the engine--oil should ooze out of the small port where you cleaned. If ok, clean the small drive-end oil passages that lead from the larger holes out to the chain groove on each side of the bar. They commonly fill with sawdust and dirt which plugs them. Clean the entire chain groove and check/oil the end sprocket if it has one. Reinstall the bar and chain, then start the engine and run the tip near some cardboard for a few moments--it should throw off a thin line of oil. Hope this helps!
Remove the bar and chain, then clean the side of the engine case where the bar fits to. Start the engine--oil should ooze out of a small port in the engine case. If ok, clean the bar and cover, then clean the two small oil channels in the drive end of the bar which allow oil to flow out into the chain groove on each side (only one is active depending on which side of the bar is 'down'). If no oil came out of the engine port, then you need to investigate the oil pump (behind the clutch), oil lines, and oil filter in the tank. The oil pump, in particular, has plastic gears that can become damaged. When oil appears at the port, assemble the bar and chain. Adjust the chain (cover fastemers finger tight) so that the chain just pulls up to the lower bar edge, but not so tight that the chain can't be pulled by hand. Make sure the teeth cut toward you on the bottom run and are properly sharpened. Tighten the cover fasteners firmly and recheck tension. If ok, run the saw at speed for several moments with the tip near some cardboard--it should throw off a thin line of oil. Hope this helps!
Depending on your knowledge and experience - 1. Find your manual and check on maintenance routines. 2. If no manual avail - clean your saw and your bar. Bar - oil holes clear, groove clean etc Saw - locate where the oil pumps out - ensure any guides, holes etc are clean. 3. If saw gas manual oil pump adjustment screw -advance the flow 4 Drain the oil tank checking for dirt etc and if necessary clean tank with a little of your fuel. 5.Refill oil tank AFTER it is clean and dry. 6. Replace bar/chain etc and test if flow is better If still no good you may need to repair/replace oil pump -not that hard to do but if in doubt take it to a reputable dealer.
OK found a complete oil pump for this saw, part number is 181245250 and if you would like to download a copy of the breakdown go to Makitatools.com and in the bottom go to Makita Canada and you can find it there. I don't know why they don't have it in the US version but that is where I got it from Good Luck and let me know if I can be of any more help
