181490-7 grease 30g 1 pcs complete be shure there are no cured o-rings or bad gaskets . 188015-8 its the maintenance kit for the service it contains already this 30 grams grease, where come 60 grams advise ? i like also to use some more grease by this heavy kind of hammers. But tools like Hilti with liquid (oil) lubrication and very tight tolerance ball bearings if there is to much (turmopol) oil used it will be damaged, and too little oil also its calculated. I cannot give garantee that 60 grams are advised by a makita service, if you order a maintenace kit ask the seller about why it only contains 30grams. The information to use 60 grams ? doubt.

As stated in the manual:The green power-ON indicator lamp lights up when the tool is plugged to the mains. If the indicator lamp is lit but the tool does not start even if the tool is switched ON, the carbon brushes may be worn out, or the motor or the switch may be defective. If the indicator lamp does not light up, the mains cord or the indicator lamp may be defective.
