א מִי שֶׁהָפַךְ אֶת זֵיתָיו אוֹ שֶׁהָיָה יֵינוֹ בַּבּוֹר, וְאֵרְעוֹ אֹנֶס אוֹ שֶׁשָּׁכַח אוֹ נִתְעַצֵּל שֶׁהָיָה סָבוּר שֶׁהָיָה יָכוֹל לִשְׁהוֹת לְאַחַר הָרֶגֶל וְלֹא עָשָׂה קֹדֶם הָרֶגֶל, מֵאַחַר שֶׁהוּא דָּבָר הָאָבֵד זוֹלֵף וְגוֹמֵר וּמְזַפֵּת הֶחָבִיּוֹת, בֵּין קְטַנּוֹת בֵּין גְּדוֹלוֹת, וְגַף (פֵּרוּשׁ שֶׁיָּשִׂים בָּהֶן מְגוּפָתָן) בֶּחָבִיּוֹת, כְּדַרְכּוֹ, בְּלֹא שִׁנּוּי; הַגָּה: וְהוּא הַדִּין דְּיָכוֹל לְתַקֵּן הֶחָבִיּוֹת לְקָשְׁרָם בַּעֲקָלִים (מָרְדְּכַי), אֲבָל לֹא יְכַוֵּן מְלַאכְתּוֹ בַּמּוֹעֵד אֶלָּא יַעֲשֶׂה הַכֹּל קֹדֶם הַמּוֹעֵד אִם יוֹדֵעַ שֶׁיִּצְטָרֵךְ בַּמּוֹעֵד (הַגָּהוֹת מיימ' וְת"ה); וְכֵן שׁוֹלֶה פִּשְׁתָּנוֹ מִן הַמִּשְׁרָה, וְכָל כַּיּוֹצֵא בָּזֶה מִדָּבָר הָאָבֵד, וּבִלְבַד שֶׁלֹּא יְכַוֵּן מְלַאכְתּוֹ בַּמּוֹעֵד.
1 Some Things with a Potential Loss, 6 Seifim: If one turned his olives or had wine in the pit and then something forced him [to not finish the process] or he forgot or he neglected to do it because he thought that it could wait until after the holiday, and he thus did not finish the process before the holiday, because there is potential loss involved, he may empty the vats [into the press], both big and little ones, and cork (meaning to put in the stopper) the vats as usual with no change [in the way it is done]. Rema: It is also the case that he can fix the vats by fixing them with wicker (Mordechai). However, he should not plan to do this work on hol hamoed. Rather, he should do everything before the holiday if he knows that it will end up being necessary on the holiday (Hagahot Maimoni and Trumat Hadeshen). He can also take his flax out of the retting, and any other similar case that involves a potential loss, as long as he does not plan to do this work on the holiday.
